From the Hebrew name
יִצְחָק (Yitzchaq) meaning
"he will laugh, he will rejoice", derived from
צָחַק (tzachaq) meaning "to laugh". The
Old Testament explains this meaning, by recounting that
Abraham laughed when God told him that his aged wife
Sarah would become pregnant with Isaac (see
Genesis 17:17), and later Sarah laughed when overhearing the same prophecy (see
Genesis 18:12). When Isaac was a boy, God tested Abraham's faith by ordering him to sacrifice his son, though an angel prevented the act at the last moment. Isaac went on to become the father of
Esau and
Jacob with his wife
Rebecca.
As an English Christian name, Isaac was occasionally used during the Middle Ages, though it was more common among Jews. It became more widespread after the Protestant Reformation. Famous bearers include the physicist and mathematician Isaac Newton (1643-1727) and the science-fiction writer Isaac Asimov (1920-1992).
