Discernment to Spiritual Danger — Gen 21:8 And the child grew, and was weaned: and Abraham made a great feast the same day that Isaac was weaned. Gen 21:9 And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking. Gen 21:10 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. Gen 21:11 And the thing was very grievous in Abraham's sight because of his son. Gen 21:12 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. Gen 21:13 And also of the son of the bondwoman will I make a nation, because he is thy seed.
