Ruth 4:18

Now these are the generations of Pharez: Pharez begat Hezron,

Now these are the generations of Pharez,.... The son of Judah, by Tamar before mentioned, Ruth 4:12, for the intention of this genealogy is to confirm the truth of Jacob's prophecy, of Shiloh the Messiah coming from the tribe of Judah, Genesis 49:10 and therefore it begins with Pharez, well known to be the son of Judah, and ends with David, whose son the Messiah was to be, as is owned by all Jews and Gentiles that believe the divine revelation:

Pharez begat Hezron; who was one of those that went down with Jacob into Egypt, being born in the land of Canaan, Genesis 47:12 called Esrom in Matthew 1:3.
