TSK · Genesis 16:2

The man said, "The woman whom you gave to be with me, she gave me of the tree, and I ate."

Sarai was barren. She had no child.

He said, "I will certainly return to you when the season comes round. Behold, Sarah your wife will have a son." Sarah heard in the tent door, which was behind him.

Isaac entreated Yahweh for his wife, because she was barren. Yahweh was entreated by him, and Rebekah his wife conceived.

She said, "Behold, my maid Bilhah. Go in to her, that she may bear on my knees, and I also may obtain children by her."

When Leah saw that she had finished bearing, she took Zilpah, her handmaid, and gave her to Jacob as a wife.

If his master gives him a wife and she bears him sons or daughters, the wife and her children shall be her master's, and he shall go out by himself.

Behold, children are a heritage of Yahweh. The fruit of the womb is his reward.
