Abraham as one hundred years of age and Sarah was about ninety years old (Gen. 17:19, 21;21:3-12; 22:2-9).
Isaac is one of the few cases in the Bible in which God selected a name for a child and announced it before he was born. In the Old Testament we have Isaac, Ishmael, Solomon, Josiah, Cyrus and Isaiah’s son; in the New Testament, John the Baptist and Jesus.
Isaac’s beautiful and suggestive name, “he laughed,” commemorates the two laughings at the promise of God—the laughing of the father’s joy and the laughing of Sarah’s incredulity which soon passed into penitence and faith (Gen. 21:6). Isaac was the child of the covenant, “I will establish My covenant with him.” To three patriarchs in succession was this covenant specifically given: to Abraham, as he left Chaldea (Gen. 12:3); toIsaac, when in Canaan during the famine (Gen. 26:4); toJacob, at Bethel (Gen. 28:14). Isaac, however, was the first to inherit the covenant, and to him God gave the whole inheritance of Abraham (Gen. 24:35).
