Genesis 22:7-8, 14

Isaac said to his father Abraham, “Father!” Abraham answered, “Yes, my son.” Isaac said, “We have the fire and the wood, but where is the lamb we will burn as a sacrifice?” Abraham answered, “God will give us the lamb for the sacrifice, my son.” So Abraham and his son went on together

So Abraham named that place The LORD Provides. Even today people say, “On the mountain of the LORD it will be provided.”
