Revelation 7:1-3

1After this I saw four angels standing at the four corners of the earth, restraining the four winds of the earth so that no wind could blow on the earth or on the sea or on any tree.

2Then I saw another angel rising up from the east, who had the seal of the living God. He cried out in a loud voice to the four angels who were allowed to harm the earth and the sea,

3“Don’t harm the earth or the sea or the trees until we seal the servants of our God on their foreheads.”
