Genesis 22:9

The place. Mount Moria, on part of which the temple was built afterwards; and on another part, called Calvary, our Saviour was crucified, having carried his cross, as Isaac did the wood for sacrifice. --- His son: having first explained to him the will of God, to which Isaac gave his free consent; otherwise, being in the vigour of his youth, he might easily have hindered his aged father, who was 125 years old, from binding him. But in this willingness to die, as in many other particulars, he was a noble figure of Jesus Christ, who was offered because it was His will. (Haydock)
