Genesis 16:2-4

LXX2012(i) 2 And Sara said to Abram, Behold, the Lord has restrained me from bearing, go therefore in to my maid, that I may get children for myself through her. And Abram listened to the voice of Sara. 3 So Sara the wife of Abram having taken Agar the Egyptian her handmaid, after Abram had lived ten years in the land of Chanaan, gave her to Abram her husband as a wife to him. 4 And he went in to Agar, and she conceived, and saw that she was with child, and her mistress was dishonored before her.
