Mark 10:8

And they twain shall be one flesh: so then they are no more twain, but one flesh.

EXPOSITORY (ENGLISH BIBLE)

Matthew Henry's Concise Commentary

10:1-12 Wherever Jesus was, the people flocked after him in crowds, and he taught them. Preaching was Christ's constant practice. He here shows that the reason why Moses' law allowed divorce, was such that they ought not to use the permission; it was only for the hardness of their hearts. God himself joined man and wife together; he has fitted them to be comforts and helps for each other. The bond which God has tied, is not to be lightly untied. Let those who are for putting away their wives consider what would become of themselves, if God should deal with them in like manner.

Gill's Exposition of the Entire Bible

And the twain shall be one flesh,.... This is the remaining part of the citation out of Genesis 2:24; See Gill on Matthew 19:5;

so then they are no more twain; but one flesh; as Adam and Eve were both by creation and marriage: and so two persons, a man and woman, being lawfully married together, become one flesh, or "one body", as the Arabic and Persic versions render the phrase; and therefore the wife is to be loved by the husband as his own body, and from whom there should be no separation, until death, but in case of adultery; See Gill on Matthew 19:6.

Geneva Study Bible

And they twain shall be one flesh: so then they are no more twain, but one flesh.

EXEGETICAL (ORIGINAL LANGUAGES)

Mark 10:8

Vincent's Word Studies

Shall be one flesh (ἔσονται εἰς σάρκα μίαν)

Lit., "shall be unto one flesh." The preposition expresses more graphically than the A. V. the becoming of one from two. So Rev., shall become.
