Abraham begat Isaac] Genesis 21:3. Matthew brings our Saviour downward from Abraham, for the comfort of the Jews, who drew their genealogies from him, because God had taken him and his seed into a peculiar covenant. Luke carries him upward unto Adam, for the comfort of the Gentiles, who were not lineally of the seed of Abraham. Isaac begat Jacob] Genesis 25:26. Jacob begat Judas] Genesis 29:35. and his brethren] These are added, not that Christ came of them, but to shew, that he esteemed himself of their kinred, and that all the tribes were included in the covenant, as well as the tribe of Judah. For this reason is Zara also named, verse 3. yet Ishmael is not added to Isaac, though he were the first born, nor Esau to Jacob, although he were born at the same time, because these belonged not to the covenant.
