Revelation 9:3-4

Then out of the smoke locusts came forth on the earth, and such power was granted them as the power the earth's scorpions have. [Exod. 10: 12-15.] They were told not to injure the herbage of the earth nor any green thing nor any tree, but only [to attack] such human beings as do not have the seal (mark) of God on their foreheads. [Ezek. 9:4.]
