Mount Moriah
God tested Abraham by telling him, "Take your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you." Abraham departed early in the morning, and on the third day, found the place the Lord showed him. He built an altar, bound Isaac on top of the wood, and took the knife to slaughter him. The angel of the Lord stops him then reaffirms the Abrahamic covenant for his obedience in not withholding even his only son from God. Instead, Abraham offered a ram provided by the Lord and named the place "The Lord will provide."
(Genesis 22)
