John Wesley on Genesis 22:13

Behold a ram - Tho' that blessed Seed was now typified by Isaac, yet the offering of him up was suspended 'till the latter end of the world, and in the mean time the sacrifice of beasts was accepted, as a pledge of that expiation which should be made by that great sacrifice. And it is observable, that the temple, the place of sacrifice, was afterward built upon this mount Moriah, 2Ch 3:1, and mount Calvary, where Christ was crucified, was not far off.
