Revelation 7:1-3

After this I saw four angels standing at the four corners of the earth, and they were restraining the four winds so that no wind would blow on the land, on the sea, or on any tree. Then I saw another angel ascending from the east, who had the seal of the living God. He shouted out with a loud voice to the four angels who had been given power to damage earth and sea, saying, “Do not damage the earth, the sea, or the trees until we have marked the loving servants of our God with a seal on their foreheads.”
