Verse 7. - And Isaac spoke to Abraham his father, - during the progress of the journey, after leaving the young men, solitude inviting him to give expression to thoughts which had been rising in his bosom, but which the presence of companions had constrained him to suppress - and said, My father: - a term of filial reverence and endearment that must have lacerated Abraham's heart. As used by Isaac it signified a desire to interrogate his parent - and he said, Here am I, my son (literally, Behold me, my son - Well, my son, what is it? in colloquial English). And he said, Behold the fire and the wood: but where is the lamb for a burnt offering. Another hint that the sacrificial system did not originate with Moses.

22:3-10 Never was any gold tried in so hot a fire. Who but Abraham would not have argued with God? Such would have been the thought of a weak heart; but Abraham knew that he had to do with a God, even Jehovah. Faith had taught him not to argue, but to obey. He is sure that what God commands is good; that what he promises cannot be broken. In matters of God, whoever consults with flesh and blood, will never offer up his Isaac to God. The good patriarch rises early, and begins his sad journey. And now he travels three days, and Isaac still is in his sight! Misery is made worse when long continued. The expression, We will come again to you, shows that Abraham expected that Isaac, being raised from the dead, would return with him. It was a very affecting question that Isaac asked him, as they were going together: My father, said Isaac; it was a melting word, which, one would think, should strike deeper in the heart of Abraham, than his knife could in the heart of Isaac. Yet he waits for his son's question. Then Abraham, where he meant not, prophesies: My son, God will provide a lamb for a burnt-offering. The Holy Spirit, by his mouth, seems to predict the Lamb of God, which he has provided, and which taketh away the sin of the world. Abraham lays the wood in order for his Isaac's funeral pile, and now tells him the amazing news: Isaac, thou art the lamb which God has provided! Abraham, no doubt, comforting him with the same hopes with which he himself by faith was comforted. Yet it is necessary that the sacrifice be bound. The great Sacrifice, which, in the fulness of time, was to be offered up, must be bound, and so must Isaac. This being done, Abraham takes the knife, and stretches out his hand to give the fatal blow. Here is an act of faith and obedience, which deserves to be a spectacle to God, angels, and men. God, by his providence, calls us to part with an Isaac sometimes, and we must do it with cheerful submission to his holy will, 1Sa 3:18.And Isaac spake unto Abraham his father,.... As they were walking together:

and said, my father; a cutting word to Abraham, who knew what he was going to do with him, so contrary to the relation and affection of a parent:

and he said, here am I, my son; what hast thou to say to me? I am ready to answer thee; he owns the relation he stood in unto him, a sense of which he had not put off, and curbs his affections, which must be inwardly moving towards him, and showed great strength of faith to grapple with such a trying exercise:

and he said, behold the fire and the wood; the fire which his father had his hand, and the wood which was upon his own, shoulders:

but where is the lamb for a burnt offering? he perceived by the preparation made, by the fire and the wood, that it was to be a burnt offering which they were going to offer; but there being no creature provided for the sacrifice, he puts this question, by which it appears that as yet he was quite ignorant of the true design of this journey, and little thought that he was to be the sacrifice: however, from what he said, it plain he had been used to sacrifices, and had been trained up in them, and had seen them performed, and knew the nature of them, and what were requisite unto them.
