Matthew 1:25

And knew her not till she had brought forth her first-born son: and he called his name JESUS--The word "till" does not necessarily imply that they lived on a different footing afterwards (as will be evident from the use of the same word in Sa1 15:35; Sa2 6:23; Mat 12:20); nor does the word "first-born" decide the much-disputed question, whether Mary had any children to Joseph after the birth of Christ; for, as LIGHTFOOT says, "The law, in speaking of the first-born, regarded not whether any were born after or no, but only that none were born before." (See on Mat 13:55-56). Next: Matthew Chapter 2

This evangelist begins with the account of Christ's parentage and birth, the ancestors from whom he descended, and the manner of his entry into the world, to make it appear that he was indeed the Messiah promised, for it was foretold that he should be the son of David, and should be born of a virgin; and that he was so is here plainly shown; for here is, I. His pedigree from Abraham in forty-two generations, three fourteens (v. 1-17). II. An account of the circumstances of his birth, so far as was requisite to show that he was born of a virgin (Mat 1:18-25). Thus methodically is the life of our blessed Saviour written, as lives should be written, for the clearer proposing of the example of them.

1:25 Until probably implies that Joseph had sexual relations with Mary after the birth of Jesus. • And Joseph named him Jesus, thus showing his acceptance of the child as his own.
