Viewing verse 10 of Genesis 21 (with context)
Read Full Chapter And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born him a son in his old age.
And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned.
¶ And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.
Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, even with Isaac.
And the thing was very grievous in Abraham’s sight because of his son.
¶ 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.
And also of the son of the bondwoman will I make a nation, because he is thy seed.
