'Wood' in the Bible

So Abraham got up early in the morning, saddled his donkey, and took two of his male servants with him, along with his son Isaac. He cut the wood for the burnt offering and set out to go to the place about which God had spoken to him.

Then Abraham took the wood for the burnt offering and placed it on his son Isaac. Abraham carried the fire and the knife. And so the two of them went on together.

Isaac addressed his father Abraham: "My father!" "I'm here, my son," Abraham replied. Isaac asked, "The fire and the wood are here, but where's the lamb for the burnt offering?"

The two of them went on together and came to the place about which God had spoken. Abraham built an altar there, arranged the wood, tied up his son Isaac, and placed him on the altar on top of the wood.
