of Rachab] This is not mentioned in the old Testament, but seems to come as a true tradition from father to son, as Jannes and Jambres resisting Moses, 2 Tim. 3. 8. and Enochs prophecie, Jude v. 14. Some think Matthew had this out of the civill tables of genealogie, which the Jews kept exactly, vers. 15.
of Ruth] This shews that the Gentiles, that were not to be destroyed, as the Moabites, of whom Ruth came, Deuteronomy 2:9. might be saved by Christ: as the mentioning of Rahab of the seed of Canaan may import, that such as remained of those that were to be cut off, Deuteronomy 7:2. might also be saved by him.
Jesse] It seems he was of no great account, because David is called in contempt, The son of Jesse, 1 Samuel 20:27; 1 Samuel 20:30-31. 1 Kings 12:16. as Christ is called, The son of Joseph, Luke 4:22.
