“And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.”
King James Version (KJV)
16:8 The fourth poured out his phial upon the sun - Which was likewise affected by the fourth trumpet. There is also a plain resemblance between the first, second, and third phials, and the first, second, and third trumpet. And it was given him - The angel. To scorch the men - Who had the mark of the beast. With fire - As well as with the beams of the sun. So these four phials affected earth, water, fire, and air.
Re 16:8,9 THE FOURTH VIAL. The fourth poured out his vial on the sun. Since these vials of the wrath of God are "poured into the earth" (Re 16:1), the sun must be used as a symbol. It is a symbol of a supreme ruler--a ruler or king. Any one who becomes a great light and occupies a pre-eminent position, may be indicated by this symbol. The Savior is described as the Sun of Righteousness (Mal 4:2). In the dream of Joseph, his father Jacob, the patriarchal ruler, is represented by the sun (Ge 37:9,10). Among the orientals it is the well-known symbol of a king or ruler. And power was given unto him to scorch men with fire. The fourth vial is poured upon this sun, and power is given it to scorch men with fire. Fire, the instrument of bitter pain, is a symbol of suffering.
