창세기 30:3의 주석

על ברכי UPON MY KNEES — as the Targum takes it: she will bear children and I will rear them.

בוא אליה, this was Rachel’s answer to her husband’s accusation. She had not meant that it was within Yaakov’s power to make her pregnant, but she wanted to nurse a child by the next best method, that of becoming foster mother to her handmaid’s child.

ותאמר הנה אמתי, She said: "here is my bondwoman, etc." She was careful to say: "my bondwoman Bilhah," before mentioning that Jacob should sleep with her, instead of saying: "sleep with my bondwoman Bilhah," as Sarai had done at the time (Genesis 16,2). I have explained there that Rachel did not mean for Bilhah to be still called a bondwoman after she had slept with Jacob. She gave Bilhah to Jacob to become a wife to him; any sons of her should be free men. Leah acted similarly when giving her bondwoman Zilpah to sleep with Jacob.
