Thematic Bible: The ruling personality in the home

So she said to Abraham, Cast out this bondwoman and her son, - for the son of this bondwoman must not inherit with my son with Isaac. And the word was very grievous in the eyes of Abraham, - on account of his son. And God said unto Abraham Let it not be grievous in thine eyes concerning the boy and concerning thy bondwoman, In all that Sarah may say unto thee, hearken to her voice, - For in Isaac, shall there be called to thee - a seed.
