On the Third Day Abraham Sees the Pillar of Fire

Yalkut Shimoni on Torah 99:4

On the third day they reached the lookout point and saw the glory of the Divine Presence standing there, as it is said, "On the third day Abraham lifted up his eyes and saw" (Genesis 22:4). He saw a pillar of fire standing from the earth to the heavens. He said to him, "Isaac, my son, do you see what I see?" He said to him, "Yes." Then Abraham understood that the lad was found acceptable for the offering.
