‏ Revelation of John 4:8

The four beasts. "The four living creatures" (Revised Version). Their common characteristics are now pointed out. All have six wings; they are full of eyes, and they all unite in a ceaseless cry of praise to God. [They were] full of eyes within. They were full of eyes before and behind, and when the wings were lifted John saw that they were full of eyes within also. The eyes, sleepless, possibly symbolize never resting, wakeful activity.

They rest not. They never rest from praising the Lord.
