Who was the son of Abraham that was almost sacrificed at Mount Moriah? Isaac. In Genesis 22, Abraham is commanded to offer his son Isaac as a sacrifice in the land of Moriah.
The episode is known as the Binding of Isaac, or the Akedah in Jewish tradition. Abraham binds Isaac and places him on an altar, but an angel of the Lord stops him before the sacrifice is completed. Abraham then sees a ram caught by its horns and offers the animal instead.
The story is commonly interpreted as a test of Abraham’s faith and obedience. It also became a major subject of Jewish and Christian interpretation, art, and religious commentary. The biblical passage does not describe Isaac as ultimately dying; he survives and later becomes the father of Esau and Jacob.
Ishmael is the main possible source of confusion because he is also Abraham’s son and features prominently in later religious traditions. However, the Hebrew Bible’s Genesis narrative explicitly identifies Isaac as the son taken to Moriah. Some Islamic traditions identify the intended son as Ishmael, so the answer can vary if the question is framed across traditions rather than specifically around Genesis.
