Revelation 4:10-11  Here the 24 Elders cast their crowns down to the feet of Almighty God in honor of His eternal reign, His creative powers and His rule over all the Universe:

10 the twenty-four elders will fall down before Him Who sits on the throne, and will worship Him Who lives forever and ever, and will cast their crowns before the throne, saying, 
11 "Worthy are You, our Lord and our God, to receive glory and honor and power; for You created all things, and because of Your will they existed, and were created."
