Revelation 4:6 and before the throne there was something like a sea of glass, like crystal; and in the center and around the throne, four living creatures full of eyes in front and behind.

Revelation 4:9 And when the living creatures give glory and honor and thanks to Him who sits on the throne, to Him who lives forever and ever,

Revelation 5:8 When He had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, each one holding a harp and golden bowls full of incense, which are the prayers of the saints.

Revelation 14:10 he also will drink of the wine of the wrath of God, which is mixed in full strength in the cup of His anger; and he will be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb.

Revelation 15:1 Then I saw another sign in heaven, great and marvelous, seven angels who had seven plagues, which are the last, because in them the wrath of God is finished. (NASB ©1995)
