John Gill's Exposition of the Whole Bible
Matthew 1:5
And Salmon begat Booz of Rachab,.... That Salmon begat Boaz, is affirmed in Ruth 4:21 but it is not there said, nor any where else in the Old Testament, as here, that he begat him of Rahab, that is, of Rahab the harlot. This the Evangelist had from tradition, or from the Jewish records. That the Messiah was to spring from Boaz is asserted by the Jewish writers s; and they also own that Rahab was married to a prince in Israel, which some say t was Joshua: they pretend that she was ten years of age when the Israelites came out of Egypt; that she played the harlot all the forty years they were in the wilderness, and was married to Joshua upon the destruction of Jericho. To excuse this marriage with a Canaanitish woman, they tell us, she was not of the seven nations with whom marriage was forbid; and moreover, that she became a proselyte when the spies were received by her: they own that some very great persons of their nation sprung from her, as Jeremiah, Maaseiah, Hanameel, Shallum, Baruch, Ezekiel, Neriah, Seraiah, and Huldah the prophetess. The truth of the matter is, she became the wife of Salmon, or Salma, as he is called, 1 Chronicles 2:11. And in the Targum on Ruth 4:20 is said to be of Bethlehem; he was the son of Nahshon or Naasson, a famous prince in Judah, and the head and captain of the tribe, Numbers 1:7 Numbers 7:12. And from Rahab sprung the Messiah, another instance of a Gentile in the genealogy of Christ; and a third follows.
And Booz begat Obed of Ruth; who was a Moabitess. It is a notion that generally obtains among the Jews u, that she was the daughter of Eglon, grandson of Balak, king of Moab; and it is often taken notice of by them w, that the king Messiah should descend from her; and also other persons of note, as David, Hezekiah, Josiah, Hananiah, Mishael, Azariah, and Daniel; wherefore the mentioning of her in this genealogy, cannot be said by them to be impertinent.
And Obed begat Jesse. Jesse is thought to be, not the immediate son of Obed, but to be of the fourth generation from him; though no others are mentioned between them in Ruth, any more than here. A Jewish writer observes x, that
"the wise men of the Gentiles say, that there were other generations between them; perhaps, says he, they have taken this from the wise men of Israel, and so it is thought.''
Now notwithstanding this, Jesse may be said to be begotten by Obed, as Hezekiah's posterity, who were carried captive into Babylon, are said to be begotten by him, Isaiah 39:7 though they were a remove of several generations from him. However, Jesse is rightly put among the progenitors of Christ, since the Messiah was to be a rod of his stem, and the branch of his roots, and is called the root of Jesse, Isaiah 11:1 which words are interpreted of the Messiah, by many of the Jewish writers y; and to this day the Jews pray for him in their synagogues under the name of בן ישי, "the son of Jesse" z.
