Amen

Wilson's Dictionary of Bible Types

Revelation 3:14 (a) This word is a word of finality. Its actual meaning is "so be it." CHRIST takes this name to indicate the permanence of His decisions, the certainty of His program, and the finality of His judgment. The angels sang a song which begins and ends with this word. It is found in Revelation 7:12. There are seven glories in this prayer or song, and these describe the perfections of GOD. Nothing can be added to this revelation, and certainly nothing may be taken from it.
