Genesis 22:2-3

“Take your son, your only son—yes, Isaac, whom you love so much—and go to the land of Moriah. Go and sacrifice him as a burnt offering on one of the mountains, which I will show you.” The next morning Abraham got up early. He saddled his donkey and took two of his servants with him, along with his son, Isaac. Then he chopped wood for a fire for a burnt offering and set out for the place God had told him about.
