Therefore she said to Abraham, Cast out this bondwoman and her son, for the son of this bondwoman shall not be an heir with my son Isaac. [Gal. 4:28-31.]
God said to Abraham, Do not let it seem grievous and evil to you because of the youth and your bondwoman; in all that Sarah has said to you, do what she asks, for in Isaac shall your posterity be called. [Rom. 9:7.]
So Abraham rose early in the morning and took bread and a bottle of water and gave them to Hagar, putting them on her shoulders, and he sent her and the youth away. And she wandered on [aimlessly] and lost her way in the wilderness of Beersheba.
Then she went and sat down opposite him a good way off, about a bowshot, for she said, Let me not see the death of the lad. And as she sat down opposite him, he lifted up his voice and wept and she raised her voice and wept.
And God heard the voice of the youth, and the angel of God called to Hagar out of heaven and said to her, What troubles you, Hagar? Fear not, for God has heard the voice of the youth where he is.
So now, swear to me here by God that you will not deal falsely with me or with my son or with my posterity; but as I have dealt with you kindly, you will do the same with me and with the land in which you have sojourned.
