Summary: God promised Abraham that a great priesthood covenant would be established
and made manifest through the lineage of a future son (B:24:11-26). As a fulfillment
of divine prophecy (B:27:20-21), Isaac was born to Abraham and his wife Sarah when
they were one hundred years and ninety years old, respectively (B:29:1-3).
Abraham had previously fathered a son named Ishmael with a woman named Hagar, Sarah’s
handmaiden (B:28:1-4). According to scripture, this turn of events was inspired by
the cunning words of one referred to as the “Son of the Morning”, who convinced Sarah
to offer Hagar to Abraham in order to fulfill the promises of God (B:27:42-54).
In speaking with Abraham, an angel foretold of enmity arising between the houses
of Ishmael and Isaac, as a result of Abraham’s “sin” (B:28:45-46,53-54).
