Matthew 1:25 Meaning and Commentary

Matthew 1:25

"And knew her not"
Or "but he knew her not", (kai) answering to the Hebrew (w) that is, had carnal knowledge of her, or copulation with her, though his wife. The words are an euphemism, or a modest way of expressing the conjugal act, and is a very ancient one, see ( Genesis 4:1 ) and what has been used in nations and languages. And this conduct of his was necessary,

till she had brought forth her firstborn;
that it might be manifest not only that she conceived, being a virgin, but also that she brought forth, being a virgin: for both are signified in the prophecy before related, "a virgin shall conceive and bring forth a son"; which is all one as if it had been said, a virgin shall conceive, and "a virgin" shall bring forth a son. The "firstborn" is that which first opens the womb of its mother, whether any follows after or not, ( Exodus 13:12 Exodus 13:13 ) ( Numbers 3:12 ) . Christ is called Mary's firstborn, because she had none before him, whether she had any after him or not; for her perpetual virginity seems to be no necessary article of faith: for when it is said,

Joseph knew her not till she had brought forth,
the meaning is certain that he knew her not before. But whether he afterwards did or not, is not so manifest, nor is it a matter of any great importance; the word "until" may be so understood as referring to the time preceding, that the contrary cannot be affirmed of the time following, ( 2 Samuel 6:23 ) ( Matthew 23:39 ) and which may be the case here, and is indeed generally understood so; and it also may be considered as only expressive of the intermediate time, as in ( Matthew 5:26 ) ( Acts 27:33 ) as Beza observes. Christ was "her firstborn" as he was man, and the firstborn of God, or his first and only begotten, as the Son of God. It is further observed, that she "called his name Jesus", as was foretold to her, or ordered her by the Angel, ( Luke 1:31 ) and to Joseph, ( Matthew 1:21 ) .

Matthew 1:25 In-Context

23 Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.
24 Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:
25 And knew her not till she had brought forth her firstborn son: and he called his name JESUS.
