“
Hagar and Ishmael Depart 8So the child grew and was weaned. And Abraham made a great feast on the same day that Isaac was weaned. 9And Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, scoffing. 10Therefore she said to Abraham, “Cast out this bondwoman and her son; for the son of this bondwoman shall not be heir with my son, namely with Isaac.” 11And the matter was very displeasing in Abraham’s sight because of his son. A Slave of a Wife Becomes a Mother! (Gen. 21:9–11) Sarai’s condition of childlessness caused her to give her female servant to Abram for procreation (Gen. 16:1–3). It is obvious from Sarai’s words, “perhaps I shall obtain children by her” (16:2), that she saw herself as the one who would be providing any eventual son from this union, even though the servant Hagar would be the mother of the child. Ancient marriage contracts obligated wives to provide a son for the married couple. Contracts dating from the mid-2nd millennium have been discovered in the city of Nuzi which specify that if a wife bore no male child she had the obligation to provide a child via a female servant. If a child was thus born to a servant, the child would be considered the child of the wife in regards to the contract. Thus, even a barren wife could fulfill her marital contract. Abram’s reluctance to send Hagar away, when Sarai became jealous of her (Gen. 21:9–11), reflects another aspect of the Nuzi tablets. Servants who provided such children were not supposed to be sent away, but rather treated favorably. So it was that it took the voice of God to convince Abram to listen to Sarai’s desire (21:12).
