It happened after these things, that God tested Abraham, and said to him, "Abraham!" He said, "Here I am." He said, "Now take your son, your only son, whom you love, even Isaac, and go into the land of Moriah. Offer him there for a burnt offering on one of the mountains which I will tell you of." Abraham rose early in the morning, and saddled his donkey, and took two of his young men with him, and Isaac his son. He split the wood for the burnt offering, and rose up, and went to the place of which God had told him. On the third day Abraham lifted up his eyes, and saw the place far off.
Genesis 22: 7-14
Isaac spoke to Abraham his father, and said, "My father?" He said, "Here I am, my son." He said, "Here is the fire and the wood, but where is the lamb for a burnt offering?" Abraham said, "God will provide himself the lamb for a burnt offering, my son." So they both went together. They came to the place which God had told him of. Abraham built the altar there, and laid the wood in order, bound Isaac his son, and laid him on the altar, on the wood. Abraham stretched forth his hand, and took the knife to kill his son. The angel of Yahweh called to him out of the sky, and said, "Abraham, Abraham!" He said, "Here I am." He said, "Don't lay your hand on the boy, neither do anything to him. For now I know that you fear God, seeing you have not withheld your son, your only son, from me." Abraham lifted up his eyes, and looked, and saw that behind him was a ram caught in the thicket by his horns. Abraham went and took the ram, and offered him up for a burnt offering instead of his son. Abraham called the name of that place Yahweh Will Provide. As it is said to this day, "On Yahweh's mountain, it will be provided."
Hebrews 11: 17-19
By faith, Abraham, being tested, offered up Isaac. Yes, he who had gladly received the promises was offering up his one and only son; even he to whom it was said, "In Isaac will your seed be called;" concluding that God is able to raise up even from the dead. Figuratively speaking, he also did receive him back from the dead.
