Genesis 21:10-12

Leeser(i) 10 Wherefore she said unto Abraham, Cast out this bond-woman and her son; for the son of this bond-woman shall not be heir with my son, with Isaac. 11 And the thing was very grievous in Abraham’s eyes, because of his son. 12 And God said unto Abraham, Let it not be grievous in thy eyes because of the lad, and because of thy bond-woman; in all that Sarah may say unto thee, hearken unto her voice; for in Isaac shall thy seed be called.
