Genesis 22:2-5

He said, “Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will 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 wood for the burnt offering, and arose and went to the place of which God had told him. On the third day Abraham raised his eyes and saw the place from a distance. Abraham said to his young men, “Stay here with the donkey, and I and the lad will go over there; and we will worship and return to you.”
