Genesis 21:9
King James Version
“And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.”
Context
6And Sarah said, God hath made me to laugh, all that hear will laugh with me.
7And she said, Who would have said unto Abraham, that Sarah should have given children suck? for I have born a son in his old age.
8And the child grew, and was weaned: and Abraham made a great feast the day that Isaac was weaned.
9And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.
10Wherefore she said unto Abraham, Cast out this bondwoman and her son: for the son of this bondwoman shall not be heir with my son, with Isaac.
11And the thing was very grievous in Abraham’s sight because of his son.
12And 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.
