Thematic Bible: The ruling personality in the home

Wherefore, she said to Abraham, Cast out this bond-woman, and her son: for the son of this bond-woman shall not be heir with my son, even with Isaac. And the thing was very grievous in Abraham's sight, because of his son. And God said to Abraham, Let it not be grievous in thy sight, because of the lad, and because of thy bond-woman; in all that Sarah hath said to thee, hearken to her voice: for in Isaac shall thy seed be called.
