Genesis 16:1-2

Darby Translation

16 And Sarai Abram's wife did not bear him [children]. And she had an Egyptian maidservant; and her name was Hagar.

² And Sarai said to Abram, Behold now, Jehovah has shut me up, that I do not bear. Go in, I pray thee, to my maidservant: it may be that I shall be built up by her. And Abram hearkened to the voice of Sarai.
