Genesis 22:2-3

God said, “Please take your son, your only son, Isaac, whom I know you dearly love, and go to the land of Moriah. Offer him up to me as a burnt offering on one of the mountains which I will show you.” Early the next morning, Abraham cut the wood for the burnt offering, loaded it on his donkey, and set out for the distant place God had shown him. He took with him two of his servants, and his son Isaac.
