Revelation 9:19

This added description of the horses supports the conclusion that they represent angelic instruments of divine judgment other than natural horses. Some interpreters have suggested that what they represent are modern weapons that shoot both forward and backward, such as missiles. The locusts had the power to injure like scorpions with their tails (Revelation 9:10), but these horses have power to kill like serpents with their tails, which is worse (cf. Revelation 9:15).
