Genesis 21:9
“And Sarah saw the son of Hagar the Egyptian, which she had born unto Abraham, mocking.”
KJV
Read in Genesis 21Meaning
Sarah observes Ishmael and reacts strongly, moving the household toward separation between Hagar's son and Isaac.
Read carefully
Translations differ over the precise nuance of Ishmael's action; the verse should not be inflated into claims the wording itself does not securely establish.
Reflection
Ambiguous details should be handled with restraint, especially when later interpretations could be used to justify hostility toward a person or group.
