Genesis 21:10
So she said to Abraham, “Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac.”
English Standard Version (ESV)
This page isn't yet indexed by search engines.
Sarah's demand isn't just about jealousy; she's asserting a clear, God-ordained truth: Ishmael, son of a servant, cannot share the inheritance of the promised heir, Isaac. This clarifies that the covenant lineage is specific and distinct, not open to mingling with those outside its divine promise.
Following the celebration of Isaac's weaning, a deeply unsettling scene unfolds: Sarah witnesses Ishmael "mocking" her son, which the text later clarifies as a form of spiritual persecution. This incident, though perhaps seemingly trivial to outsiders, ignites Sarah's fierce resolve. She insists to Abraham that Ishmael and his mother, Hagar, must be expelled from their household, not just for Isaac's immediate peace, but to definitively establish Isaac as the sole heir of God's promises.

One who receives the possessions, position, and status of another upon their death. In biblical theology, the "heir" is the one who carries forward the covenantal blessings and promises given by God.
