Genesis 22:1-3
1 Some time later God tested Abraham. He said to him, “Abraham!” “Here I am,” he replied.
2 Then God said, “Take your son, your only son, Isaac, whom you love, and go to the region of Moriah. Sacrifice him there as a burnt offering on one of the mountains I will tell you about.”
3 Early the next morning Abraham got up and saddled his donkey. He took with him two of his servants and his son Isaac. When he had cut enough wood for the burnt offering, he set out for the place God had told him about.
