Isaac stands as the second patriarch of the Israelite people, son of Abraham and Sarah and father of Esau and Jacob. Genesis 22 recounts the Akedah, where Abraham prepares to sacrifice Isaac on Mount Moriah before an angel intervenes, a narrative central to Jewish, Christian, and Islamic theology.

Medieval Europe treated Isaac as a primarily Jewish name, but the English Puritans reclaimed Old Testament names during the 17th century. Colonial American rosters show Isaac flourishing among Massachusetts Bay families from the 1630s onward, with scientists Isaac Newton and painter Isaac Oliver lending intellectual prestige.
