New Defender's Study Bible Notes
1:5 living creatures. These living creatures are later identified as the cherubs, or cherubim (Ezekiel 9:3; 10:15; etc.), who were mentioned first of all as the mighty angelic beings placed by God at the gate of the garden of Eden, to guard it after the expulsion of Adam and Eve. They seem always to be associated with the presence of God. Two images of the cherubim were made to cover the mercy seat on the ark of the covenant, where God would meet with Moses (Exodus 25:18).
