Genesis 22:6-8

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.
