one saying to the sixth angel that had one trumpet, Loose the four angels that are bound at the great river Euphrates.

And the sixth angel blew the trumpet, and I heard one voice from the horns of the golden altar [that is] before God

Then another angel [i.e., the sixth] came out of the Altar. He had authority over [its] fire and he called out in a loud voice to the one who had the sharp sickle [i.e., the fifth angel] saying, "Use your sharp sickle to gather the clusters from the vines of the earth, for its grapes are ripe."
