The Book of Jubilees 23
1And Abram rejoiced, and made all these things known to Sarai his wife; and he believed that he would have seed, but she did not bear.
2And Sarai advised her husband Abram, and said unto him: "Go in unto Hagar, my Egyptian maid: it may be that I shall build up seed unto thee by her."
3And Abram hearkened unto the voice of Sarai his wife, and said unto her, "Do (so)." And Sarai took Hagar, her maid, the Egyptian, and gave her to Abram, her husband, to be his wife.
4And he went in unto her, and she conceived and bare him a son, and he called his name Ishmael, in the fifth year of this week; and this was the eighty-sixth year in the life of Abram.
