Genesis 22:9

Abraham built an altar. Reaching the spot where in later centuries the Temple stood, father and son reared an altar. Salem, the city of Melchizedek, was scarcely more than a stone’s throw to the south. But a little farther, to the northwest, was the hill later known as Golgotha.

Bound Isaac. When all was complete, and nothing remained save the placing of the sacrifice upon the altar, Abraham tremblingly told Isaac all that God had revealed to him, and probably added to that his own faith in Isaac’s restoration. It is difficult to imagine the mingled feelings that must have surged through Isaac’s breast — amazement, terror, submission, and finally faith and trust. If such were the will of God, he would count it an honor to yield his life in sacrifice. A young man of 20, he might easily have resisted; instead, he encouraged his father in the final moments preceding the climax. That Isaac understood and shared his father’s faith was a noble tribute to the careful training he had received through childhood and youth. Isaac became thus a fitting type of the Son of God, who yielded to the will of His Father (Matt. 26:39). In each case the father gave up his only son.
