Genesis 21:10-12 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.

LXX2012⁽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 you concerning the child, and concerning the bondwoman; in all things whatever Sarrha shall say to you, hear her voice, for in Isaac shall your seed be called.
