Who was the father of Isaac?

Who was the father of Isaac? Abraham was Isaac’s father, according to the Book of Genesis. Isaac was born to Abraham and Sarah as the long-awaited child of the covenant promise.

Genesis presents Abraham and Sarah as elderly when they learn they will have a son, making Isaac’s birth a sign of divine fulfillment. His name is associated with laughter because both parents react with astonishment to the promise. Isaac later becomes one of the three patriarchs of the Israelites, alongside Abraham and Jacob.

Isaac’s family connects several major biblical figures. His half-brother is Ishmael, his wife is Rebekah, and his twin sons are Esau and Jacob. Jacob later receives the name Israel and becomes the father of the twelve tribes in biblical tradition.

Readers sometimes confuse Isaac’s father with Terah, who was Abraham’s father and therefore Isaac’s grandfather. Nahor was Abraham’s brother, while Lot was Abraham’s nephew. Those relationships make the wrong options plausible, but Abraham is the direct paternal answer.
