Genesis 16:1-3

1Now Sarai Abram’s wife bore him no children: and she had an handmaid, an Egyptian, whose name was Hagar. 2And Sarai said to Abram, Behold now, the LORD hath restrained me from bearing: I pray thee, go in to my maid; it may be that I may obtain children by her. And Abram hearkened to the voice of Sarai.1 3And Sarai Abram’s wife took Hagar her maid the Egyptian, after Abram had dwelt ten years in the land of Canaan, and gave her to her husband Abram to be his wife.
