Genesis 30:3–4

Then she said, “Here is my servant Bilhah; go in to her, so that she may give birth on my behalf, that even I may have children through her.” So she gave him her servant Bilhah as a wife, and Jacob went in to her.

Then she said, “Here is Bilhah, my servant. Sleep with her so that she can bear children for me and I too can build a family through her.”

So she gave him her servant Bilhah as a wife. Jacob slept with her,

Then she said, “Here is my maid Bilhah. Go sleep with her, and she’ll bear children for me so that through her I too can build a family.” So Rachel gave her slave Bilhah to Jacob as a wife, and he slept with her.

Then Rachel told him, “Take my maid, Bilhah, and sleep with her. She will bear children for me, and through her I can have a family, too.” So Rachel gave her servant, Bilhah, to Jacob as a wife, and he slept with her.

Then she said, “Here is my servant girl Bilhah; go in to her that she may bear children as my surrogate. Then I will even have children by her.” Then she gave him Bilhah, her female slave, as a wife, and Jacob went in to her.

And she said, Behold my maid Bilhah, go in unto her; and she shall bear upon my knees, that I may also have children by her. And she gave him Bilhah her handmaid to wife: and Jacob went in unto her.
