Genesis 21:10-12

Brenton(i) 10 then she said to Abraam, Cast out this bondwoman and her son, for the son of this bondwoman shall not inherit with my son Isaac. 11 But the word appeared very hard before Abraam concerning his son. 12 But God said to Abraam, Let it not be hard before thee concerning the child, and concerning the bondwoman; in all things whatsoever Sarrha shall say to thee, hear her voice, for in Isaac shall thy seed be called.
