And God said unto Abraham, Let it not be displeasing in your sight because of the lad, and because of your bondwoman; in all that Sarah has said unto you, listen unto her voice; for in Isaac shall your descendants be called.
And think not to say within yourselves, We have Abraham as our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.
Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham our father: for I say unto you, That God is able of these stones to raise up children unto Abraham.
