Genesis 22:5-8

5He said to his servants, ‘Stay here with the donkey. I will take the boy and we will go over there. We will worship God in that place and then we will come back to you.’

6Abraham took the wood for the burnt offering. He gave it to Isaac to carry. Abraham himself carried the fire and the knife. The two of them walked on together.

7Isaac spoke to his father, Abraham. He said, ‘Father?’ Abraham replied ‘Yes my son, what is it?’ Isaac replied, ‘I see that the fire and the wood are here. But where is the lamb so that we can make the burnt offering?’

8Abraham replied, ‘My son, God himself will bring the lamb for the burnt offering.’ The two of them continued to walk on together.
