In context
11Let the one who does wrong go on doing wrong, and the one who is vile go on being vile. Let the one who does right go on doing right, and the one who is holy go on being holy.” 12“Look, I am coming soon, and my reward is with me, to repay each one according to what they have done. 13I am the Alpha and the Omega, the first and the last, the beginning and the end. 14Blessed are those who wash their robes, so that they may have the right to the tree of life, and may enter the city through its gates. 15Outside are the dogs, the sorcerers, the sexually immoral, the murderers, the idolaters, and everyone who loves and practices falsehood.”
