Isaac, says Tabari, lived a hundred years after Ishmael. God granted him the gift of prophecy, and sent him to the inhabitants of Syria, in the country of Canaan, for he could not change his place of abode on account of his blindness; for Abimelech had wished him to be dim of sight, because Abraham had deceived him by saying, "Sarah is my sister;" and, say the Rabbis, Isaac's eyes were made dim by the tears of the angels falling into them as he was stretched upon the altar by his father; or because he had then looked upon the Throne of God, and had been dazzled thereby.
But others say he went blind through grief and tears at his son Esau having taken four Canaanitish women to wife.
Isaac had two sons, twins, by Rebekah his wife—Esau and Jacob.
The Cabbalists say that the soul of Esau, whom the Arabs call Aïs, passed into the body of Jesus Christ by metempsychosis, and that Jesus and Esau are one; and this they attempt to prove by showing that the Hebrew letters composing the name Jesus are the same as those of which Esau is compounded.[1]
The following curious story is told of the brothers by the Rabbi Eliezer:—"It is said that when Jacob and Esau were in their mother's womb, Jacob said to Esau, 'My brother, there are two worlds before us, this world and the world to come. In this world, men eat, and drink, and traffic, and marry, and bring up sons and daughters; but all this does not take place in the world to come. If you like, take this world, and I will take the other.' And Esau denied that there was a resurrection of the dead, and said, Behold I am at the point to die; and what profit shall this birthright do to me?' And he gave over to Jacob in that hour his right to the other world."[2] Therefore Esau and his descendants have no part or lot in Paradise, and none are admitted there.[3]
It is also said that the religious predilections of the children were developed before they were born. On the words of Genesis, "The children struggled together within her,"[4] a Rabbinic commentator says that when Rebekah passed before a synagogue, then Jacob made great efforts to escape into the world, that he might attend the synagogue, and this is the meaning of the words of the prophet Jeremiah, when God says of Jacob,
