In that day there will be an altar to the Lord in the heart of Egypt, and a pillar to the Lord at its border. –Isaiah 19:19
Jacob used a stone for a pillow; Jesus used a stone for a bed. We’ve seen the sort of stone manger in which He likely was laid as an infant. Later on, during the Holy Family’s sojourn in Egypt, it is believed they spent six months living in a cave near Mount Qussqam, during which time the Christ child slept on a bed of stone.
