Revelation 19:13

vesture dipped in blood-- Isa 63:2 is alluded to here, and in Rev 19:15, end. There the blood is not His own, but that of His foes. So here the blood on His "vesture," reminding us of His own blood shed for even the ungodly who trample on it, is a premonition of the shedding of their blood in righteous retribution. He sheds the blood, not of the godly, as the harlot and beast did, but of the blood-stained ungodly, including them both. The Word of God--who made the world, is He also who under the same character and attributes shall make it anew. His title, Son of God, is applicable in a lower sense, also to His people; but "the Word of God" indicates His incommunicable Godhead, joined to His manhood, which He shall then manifest in glory. "The Bride does not fear the Bridegroom; her love casteth out fear. She welcomes Him; she cannot be happy but at His side. The Lamb [Rev 19:9, the aspect of Christ to His people at His coming] is the symbol of Christ in His gentleness. Who would be afraid of a lamb? Even a little child, instead of being scared, desires to caress it. There is nothing to make us afraid of God but sin, and Jesus is the Lamb of God that taketh away the sin of the world.
