Bereshis 21:10-12

Orthodox Jewish Bible

¹⁰ Therefore she said unto Avraham, Cast out this bondwoman and her ben: for the ben of this bondwoman shall not be heir with beni (my son), even with Yitzchak.

¹¹ And the thing was very grievous in the eyes of Avraham because of bno.

¹² And Elohim said unto Avraham, Let it not be grievous in thy sight because of the na’ar, and because of thy bondwoman; in all that Sarah hath said unto thee, shema (pay heed) unto her voice; for in Yitzchak shall thy zera be called.
