Deuteronomy 31:19

Now therefore write ye this song for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.

EXPOSITORY (ENGLISH BIBLE)

Ellicott's Commentary for English Readers

(19) Put it in their mouths, that this song may be a witness.—This method of perpetuating the truth was even better adapted to the times and to the condition of the people than the delivery of a written law. It was not possible to multiply copies of the law among them to any great extent; but the rhythmical form of the song would make it easy to be retained in their memories. There is reason to believe that Samuel, the first person who (so far as we know) effected anything of importance towards the establishment of a system of religious education in Israel, employed the same means for the purpose, viz., psalms and spiritual songs. The first companies of prophets were evidently singers and minstrels (see 1Samuel 10:5-6; 1Samuel 19:20-24); hence their remarkable influence over Saul. And if they taught the psalms to the people, as they learnt them under Samuel and David—especially historical psalms, like the 78th, 105th, and 106th—a very efficacious means of spreading the knowledge of God in Israel was in their hands.

Benson Commentary

Deuteronomy 31:19. Now, therefore, write this song — Recorded in the next chapter, the contents of which were put into a song, that they might be better learned and more fixed in their minds and memories. For it has always been thought the most profitable way of instructing people, and communicating things to posterity, to put them into verse. For which reason Aristotle reports that people anciently sung their laws. And Tully tells us it was the custom of the ancient Romans to have the virtues and praises of their famous men sung at their feasts. Teach it the children of Israel — Cause them to learn and understand it, and have it daily in their mouths. That this may be a witness for me — Of my kindness in giving them so many blessings, of my patience in bearing so long with them, of my clemency in giving them such fair and plain warnings, and of my justice in punishing such an incorrigible people.

Matthew Henry's Concise Commentary

31:14-22 Moses and Joshua attended the Divine Majesty at the door of the tabernacle. Moses is told again that he must shortly die; even those who are most ready and willing to die, need to be often reminded of its coming. The Lord tells Moses, that, after his death, the covenant he had taken so much pains to make between Israel and their God, would certainly be broken. Israel would forsake Him; then God would forsake Israel. Justly does he cast those off who so unjustly cast him off. Moses is directed to deliver them a song, which should remain a standing testimony for God, as faithful to them in giving them warning, and against them, as persons false to themselves in not taking the warning. The word of God is a discerner of the thoughts and intents of men's hearts, and meets them by reproofs and correction. Ministers who preach the word, know not the imaginations of men; but God, whose word it is, knows perfectly.

Barnes' Notes on the Bible

A witness for me against them - i. e., an attestation from their own mouths at once of God's benefits, their own duties, and their deserts when they should fall away. Being in verse it would be the more easily learned and kept in memory. The use of songs for such didactic purposes was not unknown to the legislators of antiquity. Compare also the advice of Paul, "teaching and admonishing one another in psalms and hymns and spiritual songs" Colossians 3:16.

Jamieson-Fausset-Brown Bible Commentary

19. Now therefore write ye this song—National songs take deep hold of the memories and have a powerful influence in stirring the deepest feelings of a people. In accordance with this principle in human nature, a song was ordered to be composed by Moses, doubtless under divine inspiration, which was to be learnt by the Israelites themselves and to be taught to their children in every age, embodying the substance of the preceding addresses, and of a strain well suited to inspire the popular mind with a strong sense of God's favor to their nation.

Matthew Poole's Commentary

This song, which is contained Deu 32, and is put into a song that it may be better learned, and more fixed in their minds and memories.

Put it in their mouths; cause them to learn it, and sing it one to another, to oblige them to more circumspection and watchfulness.

A witness for me; of my kindness in giving them so many blessings, of my patience in bearing so long with them, of my clemency in giving them such fair and plain warnings, and my justice in punishing such an unthankful, perverse, and incorrigible people.

Gill's Exposition of the Entire Bible

Now, therefore, write ye this song for you,.... Which was now dictated by the Lord, and given to Moses and Joshua to write, which is recorded in Deuteronomy 32:1,

and teach it the children of Israel; teach them by it, instructing them in the meaning of it: thus it was usual in ancient times to write things in verses, that they might be the more pleasingly attended to and regarded, and be longer retained in memory; and especially this practice was used with children, and still is:

put it in their mouths; oblige them to get it by heart, or lay it up in their memories, and repeat it frequently, that it may be familiar to them, and not be forgotten by them:

that this song may be a witness for me against the children of Israel; when in times to come they shall call to mind how in this song they were cautioned against such and such sins, and what they were threatened with should befall them on account of them, and how all things have come to pass exactly as foretold in it; which would be a testimony for God of his goodness to them, of his tender care of them, and concern for them, in the previous cautions he gave them; and of his foreknowledge of future events; and a testimony against them for their ingratitude and other sins.

Geneva Study Bible

Now therefore write ye this {i} song for you, and teach it the children of Israel: put it in their mouths, that this song may be a witness for me against the children of Israel.

(i) To preserve you and your children from idolatry, by remembering God's benefits.

EXEGETICAL (ORIGINAL LANGUAGES)

Cambridge Bible for Schools and Colleges

19. write ye this song for you] This Pl. can be justified only by reference to Moses and Joshua both, but only Moses is addressed in Deuteronomy 31:10, and in the light of the following singular imperatives teach thou … and (Sam., LXX, Syr.) put, and of Deuteronomy 31:22, Moses (alone) wrote, read write thou … for thee. LXX has the plural throughout, Syr. repeats the Heb. text.

a witness for me against the children of Israel] By showing that God had sufficiently forewarned, and pleaded with, them (cp. Deuteronomy 31:26). Apart from the question of the date of the Song there is no doubt that Israel had been forewarned by the prophets, that they would perish if they ventured to reject His commands; and further it is generally true that no punishment for sin is ever unforeseen by the conscience of the sinner. On children of Israel, never found in D, but always editorial in Deut., see on Deuteronomy 31:23.

Pulpit Commentary

Verse 19. - Write ye this song. This refers to the song which follows in next chapter. Moses and Joshua were both to write this song, Moses probably as the author, Joshua as his amanuensis, because both of them were to do their endeavor to keep the people from that apostasy which God had foretold. Deuteronomy 31:19

Keil and Delitzsch Biblical Commentary on the Old Testament

"And now," sc., because what was announced in Deuteronomy 31:16-18 would take place, "write you this song." "This" refers to the song which follows in ch. 32. Moses and Joshua were to write the song, because they were both of them to strive to prevent the apostasy of the people; and Moses, as the author, was to teach it to the children of Israel, to make them learn it, that it might be a witness for the Lord (for Me) against the children of Israel. "This" is defined still further in Deuteronomy 31:20, Deuteronomy 31:21 : if Israel, through growing satisfied and fat in its land, which was so rich in costly good, should turn to other gods, and the Lord should visit it in consequence with grievous evils and troubles, the song was to answer before Israel as a witness; i.e., not only serve the Lord as a witness to the people that He had foretold all the evil consequences of apostasy, and had given Israel proper warning (Knobel), but to serve, as we may see from Deuteronomy 31:20, Deuteronomy 31:21, and from the contents of the song, as a witness, on the one hand, that the Lord had conferred upon the people so many benefits and bestowed upon them such abundant blessings of His grace, that apostasy from Him was the basest ingratitude, for which they would justly be punished; and, on the other hand, that the Lord had not rejected His people in spite of the punishments inflicted upon them, but would once more have compassion upon them and requite their foes, and thus would sanctify and glorify Himself as the only true God by His judgments upon Israel and the nations. The law, with its commandments, promises, and threats, was already a witness of this kind against Israel (cf. Deuteronomy 31:26); but just as in every other instance the appearance of a plurality of unanimous witnesses raises the matter into an indisputable truth, so the Lord would set up another witness against the Israelites besides the law, in the form of this song, which was adapted to give all the louder warning, "because the song would not be forgotten out of the mouths of their seed" (Deuteronomy 31:21). The song, when once it had passed into the mouths of the people, would not very readily vanish from their memory, but would be transmitted from generation to generation, and be heard from the mouths of their descendants, as a perpetual warning voice, as it would be used by Israel for God knew the invention of the people, i.e., the thoughts and purposes of their heart, which they cherished (עשׂה used to denote the doing of the heart, as in Isaiah 32:6) even then before He had brought them into Canaan. (On Deuteronomy 31:20, vid., Deuteronomy 7:5; Deuteronomy 9:5, and Exodus 3:8.) - In Deuteronomy 31:22 the result is anticipated, and the command of God is followed immediately by an account of its completion by Moses (just as in Exodus 12:50; Leviticus 16:34, etc.). - After this command with reference to the song, the Lord appointed Joshua to the office which he had been commanded to take, urging him at the same time to be courageous, and promising him His help in the conquest of Canaan. That the subject to ויצו is not Moses, but Jehovah, is evident partly from the words themselves, "I will be with thee' (vid., Exodus 3:12). (Note: Knobel's assertion (on Numbers 27:23) that the appointment of Joshua on the part of Moses by the imposition of hands, as described in that passage, is at variance with this verse, scarcely needs any refutation. Or is it really the case, that the installation of Joshua on the part of God is irreconcilable with his ordination by Moses?)
