Charles Spurgeon Commentary Genesis 22:6-8

"And Abraham took the wood of the burnt-offering, and laid it upon Isaac his son. And he took in his hand the fire and the knife. And they went both of them together. And Isaac spake unto Abraham his father, and said, My father. And he said, Here am I, my son. And he said, Behold, the fire and the wood. But where is the lamb for a burnt-offering? And Abraham said, God will provide himself the lamb for a burnt-offering, my son. So they went both of them together." — Genesis 22:6-8 (ASV)

And they went both of them together. And Isaac spake unto Abraham his father, and said, My father: and he said, Here am I, my son. And he said, Behold the fire and the wood: but where is the lamb for a burnt offering? And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together.

Abraham here spoke like a prophet; in fact, throughout this whole incident, he never opened his mouth without a prophetic utterance. I believe that, when men walk with God, and live near to God, they will possibly even without being aware of it, speak very weighty words which will have much more in them than they themselves apprehend. Is it not written, concerning the man whose delight is in the law of the Lord, his leaf also shall not wither? Not only shall his fruit be abundant, but his casual word, his leaf also shall not wither. So it was with Abraham.

He spoke like a prophet of God when he was really speaking to his son in the anguish of his spirit, and in his prophetic utterance we find the sum and substance of the gospel: My son, God will provide himself a lamb for a burnt offering. He is the great Provider, and he provides the offering, not only for us, but for himself, for the sacrifice was necessary to God as well as to man. And it is a burnt offering, not only a sin-offering but an offering of a sweet savor to himself.

So they went both of them together. Twice we are told this, for this incident is a type of the Father going with the Son and the Son going with the Father up to the great sacrifice on Calvary. It was not Christ alone who willingly died, or the Father alone who gave his Son, but they went both of them together, even as Abraham and Isaac did here.
