Genesis 21:12

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.

And God said unto Abraham, Let it not be grievous in thy sight because of the lad, and because of thy bondwoman; in all that Sarah hath said unto thee, hearken unto her voice; for in Isaac shall thy seed be called.

God said to Abraham, “Don’t let it be grievous in your sight because of the boy, and because of your servant. In all that Sarah says to you, listen to her voice. For your offspring will be named through Isaac.
