Laughter, Genesis 17:17 18:12 21:6, one of the patriarchal ancestors of the Hebrew nation and of Christ, son of Abraham and Sarah, B. C. 1896-1705. His history is related in Genesis 21:1-34 24:1-28:22 35:27-29. He is memorable for the circumstances attending his birth, as a child of prophecy and promise, in the old age of his parents. Even in childhood he was the object of dislike to his brother Ishmael, son of the bondwoman; and in this, a type of all children of the promise, Galatians 4:29. Trained in the fear of God to early manhood, he showed a noble trust and obedience in his conduct during that remarkable trail of faith which established Abraham as the "father of the faithful;" and in his meek submission to all the will of God, prefigured the only-begotten Son of the Father. At the age of forty, he married the pious and lovely Rebekah of Mesopotamia. Most of his life was spent in the southern part of Canaan and its vicinity. At the burial of his father, he as joined by his outcast brother Ishmael. Two sons of Isaac are named in Scripture. The partiality of the mother for Jacob, and of the father for Esau, led to unhappy jealousies, discord, sin, and long separations between the brothers, though all were overruled to accomplish the purposed of God. At the age of one hundred and thirty-seven, Isaac blessed Jacob and sent him away into Mesopotamia. At the age of one hundred and eighty, he died, and was buried in the tomb of Abraham by his two sons. In his natural character, Isaac was humble, tranquil, and meditative; in his piety, devout, full of faith, and eminently submissive to the will of God.
