After this I [John] saw
four angels standing at the four corners of the earth. They were holding back the four winds of the earth to keep them from blowing on the land, the sea, or any tree. 


       I saw another angel coming from the east with the seal of the living God. 

           He cried out in a loud voice to the four angels who had been allowed to harm the land and sea,  “Don’t harm the land, the sea, or the trees until we have put the seal on the foreheads of the servants of our God.”
