On the Ark were the Cherubim with their faces of boys and their wings. Their number was two, corresponding to the two tables, and to the two sacred names of God, Adonai and Elohim, which characterized Him as benevolent and as powerful. The face of each Cherub measured one span, and the wings extended each ten spans, making twenty-two spans in all, corresponding to the twenty-two letters of the Hebrew alphabet.
It was "from between the two Cherubim" that God communed with Moses, for the Shekinah never wholly descended to earth any more than any mortal ever quite mounted into the heaven, even Moses and Elijah stood a slight distance from heaven; for, "The heaven, even the heavens, are the Lord's: but the earth hath He given to the children of men." Therefore God chose the Cherubim that were ten spans above the earth as the place where the Shekinah betook itself to commune with Moses.
The heads of the Cherubim were slightly turned back, like that of a scholar bidding his master farewell; but as a token of God's delight in His people Israel, the faces of the Cherubim, by a miracle, "looked one to another" whenever Israel were devoted to their Lord, yea, even clasped one another like a loving couple. During the festivals of the pilgrimage the priest used to raise the curtain from the Holy of Holies to show the pilgrims how much their God loved them as they could see in the embrace of the two Cherubim.
