Following the sixth Trumpet Judgment (9:13-21) the Apostle John saw another mighty angel. This is another angel (Grk., "another of the same kind") distinct from the sixth angel who sounded the sixth trumpet (9:13). He is coming down from heaven emphasizing his origin and his heavenly authority. Clouds are often associated with divine intervention and judgment (Dan. 7:13; 1 Thess. 4:17). His being clothed with a cloud symbolizes his role in executing God's judgment. The rainbow encircling his head reminds us of the rainbow around God’s throne and signals this angel is acting with divine authority (4:3). His face reflects God’s Shekinah glory and his legs like pillars of fire symbolize divine judgment.
The little scroll open in his hand is not the seven-sealed scroll of 5:1. A different word is used in the Greek to distinguish this scroll from the former. Based on what happens in this vision, this little scroll contains revelation concerning the final series of judgments, the Bowl Judgments.
