Genesis 22:1-9

Now after these things, God tested [the faith and commitment of] Abraham and said to him, “Abraham!” And he answered, “Here I am.” God said, “Take now your son, your only son [of promise], whom you love, Isaac, and go to the region of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you.” So Abraham got up early in the morning, saddled his donkey, and took two of his young men with him and his son Isaac; and he split the wood for the burnt offering, and then he got up and went to the place of which God had told him. On the third day [of travel] Abraham looked up and saw the place in the distance. Abraham said to his servants, “Settle down and stay here with the donkey; the young man and I will go over there and worship [God], and we will come back to you.” [Heb 11:17-19] Then Abraham took the wood for the burnt offering and laid it on [the shoulders of] Isaac his son, and he took the fire (firepot) in his own hand and the [sacrificial] knife; and the two of them walked on together. And Isaac said to Abraham, “My father!” And he said, “Here I am, my son.” Isaac said, “Look, the fire and the wood, but where is the lamb for the burnt offering?” Abraham said, “My son, God will provide for Himself a lamb for the burnt offering.” So the two walked on together. When they came to the place of which God had told him, Abraham built an altar there and arranged the wood, and bound Isaac his son and placed him on the altar, on top of the wood. [Matt 10:37]
