Isaac /ˈaɪzɪk, zək/
n : (Old Testament) the second patriarch; son of Abraham and
Sarah who was offered by Abraham as a sacrifice to God;
father of Jacob and Esau
laughter. (1) Israel, or the kingdom of the ten tribes (Amos
(2.) The only son of Abraham by Sarah. He was the longest
lived of the three patriarchs (Gen. 21:1-3). He was circumcised
when eight days old (4-7); and when he was probably two years
old a great feast was held in connection with his being weaned.
The next memorable event in his life is that connected with
the command of God given to Abraham to offer him up as a
sacrifice on a mountain in the land of Moriah (Gen. 22). (See ABRAHAM.) When he was forty years of age Rebekah was
chosen for his wife (Gen. 24). After the death and burial of his
father he took up his residence at Beer-lahai-roi (25:7-11),
where his two sons, Esau and Jacob, were born (21-26), the
former of whom seems to have been his favourite son (27,28).
In consequence of a famine (Gen. 26:1) Isaac went to Gerar,
where he practised deception as to his relation to Rebekah,
imitating the conduct of his father in Egypt (12:12-20) and in
Gerar (20:2). The Philistine king rebuked him for his
After sojourning for some time in the land of the Philistines,
he returned to Beersheba, where God gave him fresh assurance of
covenant blessing, and where Abimelech entered into a covenant
of peace with him.
The next chief event in his life was the blessing of his sons
(Gen. 27:1). He died at Mamre, "being old and full of days"
(35:27-29), one hundred and eighty years old, and was buried in
the cave of Machpelah.
In the New Testament reference is made to his having been
"offered up" by his father (Heb. 11:17; James 2:21), and to his
blessing his sons (Heb. 11:20). As the child of promise, he is
contrasted with Ishmael (Rom. 9:7, 10; Gal. 4:28; Heb. 11:18).
Isaac is "at once a counterpart of his father in simple
devoutness and purity of life, and a contrast in his passive
weakness of character, which in part, at least, may have sprung
from his relations to his mother and wife. After the expulsion
of Ishmael and Hagar, Isaac had no competitor, and grew up in
the shade of Sarah's tent, moulded into feminine softness by
habitual submission to her strong, loving will." His life was so
quiet and uneventful that it was spent "within the circle of a
few miles; so guileless that he let Jacob overreach him rather
than disbelieve his assurance; so tender that his mother's death
was the poignant sorrow of years; so patient and gentle that
peace with his neighbours was dearer than even such a coveted
possession as a well of living water dug by his own men; so
grandly obedient that he put his life at his father's disposal;
so firm in his reliance on God that his greatest concern through
life was to honour the divine promise given to his race.",
