Genesis 16:2; Genesis 20:18

2 And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in unto my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.

18 For the LORD had fast closed up all the wombs of the house of Abimelech, because of Sarah Abraham's wife.
