Exodus 20:25

And if thou wilt make me an altar of stone, thou shalt not build it of hewn stone: for if thou lift up thy tool upon it, thou hast polluted it.

EXPOSITORY (ENGLISH BIBLE)

Ellicott's Commentary for English Readers

(25) If thou wilt make me an altar of stone.—Among civilised nations altars were almost always of stone, which superseded earth, as more durable. God does not absolutely prohibit the employment of stone altars by the Israelites, who are found to use them upon certain occasions (Joshua 8:31; 1Kings 18:32). He is content to forbid the shaping of the stones by an implement, that so they may not give rise to idolatry. (See Note on Exodus 20:24.)

Thou hast polluted it.—Nature is God’s handiwork, and, therefore, pure and holy. Man, by contact with it, imparts to it of his impurity. The altar, whereby sin was to be expiated, required to be free from all taint of human corruption. For the construction of the altar afterwards sanctioned, see the comment on Exodus 27:1.

Matthew Henry's Concise Commentary

20:22-26 Moses having entered into the thick darkness, God there spake in his hearing all that follows from hence to the end of chap. 23, which is mostly an exposition of the ten commandments. The laws in these verses relate to God's worship. The Israelites are assured of God's gracious acceptance of their devotions. Under the gospel, men are encouraged to pray every where, and wherever God's people meet in his name to worship him, he will be in the midst of them; there he will come unto them, and will bless them.

Barnes' Notes on the Bible

Nothing could be more appropriate as the commencement of the book of the covenant than these regulations for public worship. The rules for the building of altars must have been old and accepted, and are not inconsistent with the directions for the construction of the altar of the court of the tabernacle, Exodus 27:1-8 (compare Joshua 22:26-28).

Jamieson-Fausset-Brown Bible Commentary

25. thou shalt not build it of hewn stone, &c.—that is, carved with figures and ornaments that might lead to superstition.

Matthew Poole's Commentary

An altar of stone in those rocky parts might be as easy for them to make as one of earth. Hewn stone would require both time, and cost, and art. The reasons of this precept are in part the same with the former, Exodus 20:24.

If thou lift up thy tool upon it, thou hast polluted it, by thy disobedience to my express command now given; and howsoever they think to gratify me by this curiosity, I shall not look upon it as a sacred thing, by which the sacrifices offered on it shall be sanctified, but as a profane thing which will defile them. So little doth God value or approve the inventions of men in his worship, how colourable soever they be.

Gill's Exposition of the Entire Bible

And if thou wilt make me an altar of stone,.... If they chose instead of an earthen one to make one of stone, as they might in rocky places, where they came, and in such an one where they now were, Mount Sinai, under which hill an altar was built, Exodus 24:4,

thou shall not build it of hewn stone; which would require time and occasion expense, to hew and polish them in an artificial way; but it was to be built of rude and unpolished stones, just as they were taken out of the quarry, or found lying by the way, and which were laid up in an heap one upon another, and was done with little trouble, and without any ornament, and easily separated and thrown down, when become useless: the reason of this law, as given by Maimonides (w), is this,"because the idolaters of that time built their altars of hewn stones, therefore God forbad it, lest we should be like them, and that we might shun it in all things, he commanded the altar to be made of earth, as it is said, an altar of earth shalt thou make unto me; and if it could not be made without stones, that the stones should remain in their own natural form, and be neither hewn nor polished; as he after forbad a painted stone, and a plantation of trees by an altar; for in each of these there is one and the same intention and design, namely, that we might not worship him in the same manner in which idolaters used to worship their fictitious deities:"

for if thou lift up thy tool upon it; or, thy sword (x); it signifies any tool or instrument made of iron as a sword is, and here such an one as is used in hewing of stone; which, if lifted up on the altar, or on any of the stones of which it is built, to strike and hew them with:

thou hast polluted it; and so made it unfit for use: how this should be done hereby is not easy to say, no good reason seems to be assignable for it but the will and pleasure of God; who so appointed it, and reckoned that a pollution, and would have it so thought by others, which with men is accounted ornamental; his thoughts and judgment are not as man's: the Targum of Jonathan is,"for if thou liftest up iron, of which a sword is made, upon a stone, thou wilt profane it;''the reason which the Misnic doctors (y) give, and Jarchi from them, is,"because iron was created to shorten the days of men, but the other was made to prolong the days of men: and therefore it cannot be just that that which shortens should be lifted up and agitated over that which prolongs:''but Maimonides gives a better reason of it, as Abarbinel understands him, which was to prevent persons making images in stones (z), which image making is the thing guarded against and forbidden in the context; but still better is that of Isaac Arama (a), that the hands of the artificer were to abstain from the stones of the altar, lest that good which men obtain of God at the altar should be attributed to any work of theirs: though, after all, it is right what Aben Ezra, says, that it does not belong to us to search after the reasons of the commands, at least not in too curious and bold a manner, and where God is silent and has not thought fit to give any.

And if thou wilt make me an altar of stone, thou shalt not build it of hewn stone: for if thou lift up thy tool upon it, thou hast polluted it.

EXEGETICAL (ORIGINAL LANGUAGES)

Cambridge Bible for Schools and Colleges

25. tool] The word (ḥéreb) commonly rendered ‘sword,’ occasionally used of other sharp instruments, Joshua 5:2-3 (‘knives’): in Deuteronomy 27:5 E (Joshua 8:31) the word is replaced by ‘iron.’ Cf. 1Ma 4:47. The prohibition may be a survival either from a time when instruments of iron were not in general use, or from the time when the altar was a natural rock or boulder (cf. on v. 24), supposed to be the abode of numen or deity, and it was imagined that to alter its shape would have the effect of driving the numen from it (Nowack, Arch. ii. 17; DB. i. 76a, EB. i. 124). But naturally this is not the belief which actuates the prohibition here. An altar of stones, seemingly unhewn, was built by Elijah (1 Kings 18:32).

it (twice)] The pron. (which is fem. in the Heb.) refers not to ‘altar but to ‘stone’: it is the stone which is profaned by being worked with a tool.

Pulpit Commentary

Verse 25. - And if thou wilt make me an altar of stone - i.e., if, notwithstanding my preference expressed for an altar of earth, thou wilt insist on making me one of stone, as more permanent, and so more honourable, then I require that the stones shall be rough stones shaped by nature, not stones chiselled into shape by the art of man. For if thou lift up thy tool upon it thou hast polluted it. It is conjectured with reason that we have here an old traditional idea, which God thought fit under the existing circumstances to sanction. The real object was that altars should not be elaborately carved with objects that might superinduce idolatry. The widely prevalent notion, that nature is sacred, and that all man's interference with nature is a defilement, was made use of economically, to produce the desired result. No tool being allowed to be used, no forms of living creatures could be engraved, and so no idolatry of them could grow up. Exodus 20:25

Keil and Delitzsch Biblical Commentary on the Old Testament

For the worship of Jehovah, the God of heaven, Israel needed only an altar, on which to cause its sacrifices to ascend to God. The altar, as an elevation built up of earth or rough stones, was a symbol of the elevation of man to God, who is enthroned on high in the heaven; and because man was to raise himself to God in his sacrifices, Israel also was to make an altar, though only of earth, or if of stones, not of hewn stones. "For if thou swingest thy tool (חרב lit., sharpness, then any edge tool) over it (over the stone), thou defilest it" (Exodus 20:25). "Of earth:" i.e., not "of comparatively simple materials, such as befitted a representation of the creature" (Schultz on Deuteronomy 12); for the altar was not to represent the creature, but to be the place to which God came to receive man into His fellowship there. For this reason the altar was to be made of the same material, which formed the earthly soil for the kingdom of God, either of earth or else of stones, just as they existed in their natural state; not, however, "because unpolished stones, which retain their true and native condition, appear to be endowed with a certain native purity, and therefore to be most in harmony with the sanctity of an altar" (Spencer de legg. Hebr. rit. lib. ii. c. 6), for the "native purity" of the earth does not agree with Genesis 3:17; but because the altar was to set forth the nature of the simple earthly soil, unaltered by the hand of man. The earth, which has been involved in the curse of sin, is to be renewed and glorified into the kingdom of God, not by sinful men, but by the gracious hand of God alone. Moreover, Israel was not to erect the altar for its sacrifices in any place that it might choose, but only in every place in which Jehovah should bring His name to remembrance. וגו שׁם הזכּיר does not mean "to make the name of the Lord remembered," i.e., to cause men to remember it; but to establish a memorial of His name, i.e., to make a glorious revelation of His divine nature, and thereby to consecrate the place into a holy soil (cf. Exodus 3:5), upon which Jehovah would come to Israel and bless it. Lastly, the command not to go up to the altar by steps (Exodus 20:26) is followed by the words, "that thy nakedness be not discovered thereon." It was in the feeling of shame that the consciousness of sin first manifested itself, and it was in the shame that the sin was chiefly apparent (Genesis 3:7); hence the nakedness was a disclosure of sin, through which the altar of God would be desecrated, and for this reason it was forbidden to ascend to the altar by steps. These directions with reference to the altar to be built do not refer merely to the altar, which was built for the conclusion of the covenant, nor are they at variance with the later instructions respecting the one altar at the tabernacle, upon which all the sacrifices were to be presented (Leviticus 17:8-9; Deuteronomy 12:5.), nor are they merely "provisional" but they lay the foundation for the future laws with reference to the places of worship, though without restricting them to one particular locality on the one hand, or allowing an unlimited number of altars on the other. Hence "several places and altars are referred to here, because, whilst the people were wandering in the desert, there could be no fixed place for the tabernacle" (Riehm). But the erection of the altar is unquestionably limited to every place which Jehovah appointed for the purpose by a revelation. We are not to understand the words, however, as referring merely to those places in which the tabernacle and its altar were erected, and to the site of the future temple (Sinai, Shilloh, and Jerusalem), but to all those places also where altars were built and sacrifices offered on extraordinary occasions, on account of God, - appearing there such, for example, as Ebal (Joshua 8:30 compared with Deuteronomy 27:5), the rock in Ophrah (Judges 6:25-26), and many other places besides.
