The Lord Will Provide

Now it came to pass after these things that God tested Abraham, and said to him, "Abraham!" And he said, "Here I am." Then He said, "Take now your son, your only [son] Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you." So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him, and Isaac his son; and he split the wood for the burnt offering, and arose and went to the place of which God had told him. Then on the third day Abraham lifted his eyes and saw the place afar off. And Abraham said to his young men, "Stay here with the donkey; the lad and I will go yonder and worship, and we will come back to you." So Abraham took the wood of the burnt offering and laid [it] on Isaac his son; and he took the fire in his hand, and a knife, and the two of them went together. But Isaac spoke to Abraham his father and said, "My father!" And he said, "Here I am, my son." Then he said, "Look, the fire and the wood, but where [is] the lamb for a burnt offering?" And Abraham said, "My son, God will provide for Himself the lamb for a burnt offering." So the two of them went together. Then they came to the place of which God had told him. And Abraham built an altar there and placed the wood in order; and he bound Isaac his son and laid him on the altar, upon the wood. And Abraham stretched out his hand and took the knife to slay his son. But the Angel of the LORD called to him from heaven and said, "Abraham, Abraham!" So he said, "Here I am." And He said, "Do not lay your hand on the lad, or do anything to him; for now I know that you fear God, since you have not withheld your son, your only [son], from Me." Then Abraham lifted his eyes and looked, and there behind [him was] a ram caught in a thicket by its horns. So Abraham went and took the ram, and offered it up for a burnt offering instead of his son. (Genesis 22:1-13 NKJV)
By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises offered up his only begotten [son], of whom it was said, "In Isaac your seed shall be called," concluding that God [was] able to raise [him] up, even from the dead, from which he also received him in a figurative sense. (Hebrews 11:17-19 NKJV)
