Hebrews 11:17
By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son.
By faith Abraham, when he was tried, .... Or tempted; that is, by God, Genesis 22:1. This temptation or trial respects the command given by God to Abraham, to offer up his son Isaac; which lays no foundation for a charge against God, either of sin or cruelty; for God's will is the rule of justice and goodness, and whatever he requires is just and good; and though his creatures are bound by the laws he prescribes them, he himself is not: besides, he is the Lord of life, the giver and preserver of it; and he has a right to dispose of it, and to take it away, when, and by what means, and instruments, he thinks fit; to which may be added, that the secret will of God was not that Isaac should die, but a command was given to Abraham to offer him up, for the trial of his faith and love; this was a temptation of probation, not of seduction, or to sin, as are the temptations of Satan; for God tempts no man with sin. The Jews speak {x} of ten temptations, with which Abraham was tried, and in all which he stood; and say, that this of the binding of Isaac was the tenth and last.
offered up Isaac; he showed great readiness to do it; as soon as he had the command given him, he travelled three days' journey in order to it; took the wood of the burnt offering, and laid it on his son; took fire, and a knife in his hand, with the one to burn the wood, with the other to slay his son; he built an altar, laid the wood in order on it; and bound his son, and laid him on that; and took the knife, and stretched forth his hand to slay him, and fully intended to do it, had he not been prevented: and all this he did by faith; he believed the equity, justice, and wisdom of the divine command; he was fully assured of the truth and faithfulness of God in his promises, however contrary this might seem thereunto; and he was strongly persuaded of the power of accomplishing them in some way or another. This was great faith, and it was greatly tried, as follows:
and he that had received the promises offered up his only begotten son; he had a promise made him that he should have a son, and that a numerous issue should spring from him, which should inherit the land of Canaan; yea, that the Messiah himself should be of his seed: and he had received these promises; given credit to them, and firmly believed them, and fully expected the performance of them; as he had reason to do, since the first was fulfilled, the son was born; and yet now he is called to offer him up, on whom his expectation was placed; everything was trying; it was an human creature he was called to offer, whose blood is not to be shed by man; a child of his own, a part of himself; a son, an own son; an only begotten son; a son whom he loved; an Isaac, a son of joy; a son of promise; and his heir, the son of his old age, and who was now a grown up person. The Jews are divided about the age of Isaac at his binding: Josephus {y} says he was twenty five years of age; others say twenty six {z}; some say {a} thirty six: but the more prevailing opinion is {b}, that he was thirty seven years of age; only Aben {c} Ezra makes him to be about thirteen; rejecting the more commonly received account, as well as that he was but five years old, that being an age unfit to carry wood. Some Christian writers have thought he might be about three and thirty years of age, the age of Christ when he suffered, of whom he was a type.
