창세기 16:11의 미드라쉬

Abraham, modest and unassuming as he was, was ready to do justice to Sarah, and he conferred full power upon her to dispose of Hagar according to her pleasure. He added but one caution, "Having once made her a mistress, we cannot again reduce her to the state of a bondwoman." Unmindful of this warning, Sarah exacted the services of a slave from Hagar. Not alone this, she tormented her, and finally she cast an evil eye upon her, so that the unborn child dropped from her, and she ran away. On her flight she was met by several angels, and they bade her return, at the same time making known to her that she would bear a son who should be called Ishmael--one of the six men who have been given a name by God before their birth, the others being Isaac, Moses, Solomon, Josiah, and the Messiah.

Balaam said: Of the seventy nations that the Holy One, blessed be He, created in His world, He did not put His name on any one of them except on Israel; and since the Holy One, blessed be He, made the name of Ishmael similar to the name of Israel, woe to him who shall live in his days, as it is said, "Alas, who shall live when God establisheth him?" (Num. 24:23).

Whence do we know about Ishmael? Because it is said, "And the angel of the Lord said unto her, Behold, thou art with child,… and thou shalt call his name Ishmael" (Gen. 16:11). Why was his name || called Ishmael? Because in the future the Holy One, blessed be He, will hearken to the cry of the people arising from (the oppression) which the children of Ishmael will bring about in the land in the last (days); therefore was his name called Ishmael.

(5) And Sarai said to Avram: My anger is on you! (Genesis 16:5) Rabbi Yudan says, in the name of Rabbi Yehudah bar Simon: You made violence on me with your words. Why? Because you heard my being despised and you were silent. Rabbi Berachia in the name of Rabbi Aba bar Kahana said: I have a grievance against you! This is similar to two men who are imprisoned, and when the king passes through one says: King! Make justice for me! The king says to let him go. His companion said: I have a grievance against you! If you had said 'make justice for us' both of us would be free, but since you said 'make justice for me' he released you but not me. So too, had you [Avram] said "and we go childless" just as you got a child I would have gotten a child. But since you said "and I go childless" (Genesis 15:2) you received a child but not I. ... Rabbi Tanchuma said, in the name of Rabbi Chiyah... whoever runs after the characteristic of judgment does not escape its hands. Sarah should have reached the same age as Avraham, but because she said "may God judge between you and me" (Genesis 16:5) 38 years were deducted from her. Behold, it is written "And he came to Hagar, and she conceived" (Genesis 16:4) but it also says "behold you are pregnant and you will give birth to a son"(Genesis 16:11) it teaches you that Sarah set the evil eye upon Hagar, and she miscarried. Rabbi Chanina said: even if just the prophet Elisha had said that to her it would have been enough, rather, she merited to receive these news through the angel.
