Revelation 4:6-11 (HCSB)
6 Something like a sea of glass, similar to crystal, was also before the throne. Four living creatures covered with eyes in front and in back were in the middle[a] and around the throne. 7 The first living creature was like a lion; the second living creature was like a calf; the third living creature had a face like a man; and the fourth living creature was like a flying eagle. 8 Each of the four living creatures had six wings; they were covered with eyes around and inside. Day and night they never stop,[b]saying:
Holy, holy, holy,[c]
Lord God, the Almighty,
who was, who is, and who is coming.
9 Whenever the living creatures give glory, honor, and thanks to the One seated on the throne, the One who lives forever and ever, 10 the 24 elders fall down before the One seated on the throne, worship the One who lives forever and ever, cast their crowns before the throne, and say:
11 Our Lord and God,[d]
You are worthy to receive
glory and honor and power,
because You have created all things,
and because of Your will
they exist and were created.
