Genesis 22:3-8

Abraham got up early in the morning and saddled his donkey. He took two of his young servants and his son Isaac. He had split wood for the burnt offering. He set out for the place God had directed him. On the third day he looked up and saw the place in the distance. Abraham told his two young servants, “Stay here with the donkey. The boy and I are going over there to worship; then we’ll come back to you.” Abraham took the wood for the burnt offering and gave it to Isaac his son to carry. He carried the flint and the knife. The two of them went off together. Isaac said to Abraham his father, “Father?” “Yes, my son.” “We have flint and wood, but where’s the sheep for the burnt offering?” Abraham said, “Son, God will see to it that there’s a sheep for the burnt offering.” And they kept on walking together.
