10:1 mighty angel. The description of this “mighty angel” makes it obvious that He is none other than Christ Himself (compare with Revelation 1:7,16,15). John has seen Him first as the glorified Son of man (Revelation 1:13), then as God upon the throne (Revelation 4:10), the Lamb with the title scroll (Revelation 5:8), and the conquering Rider on the white horse (Revelation 6:2). Now He appears as the mighty Angel of the Lord, claiming possession of land and sea.
10:1 rainbow. The beautiful rainbow, an eloquent representation of both divine judgment and mercy in judgment, was first seen above the emerald throne and the One who sat upon the throne (Revelation 4:3), in heaven. Now, near the very middle of the tribulation, He descends to the earth, and the rainbow is still above His head as a glorious crown.
