The back-translation of Isaiah 33:15 from Alur is as follows:
“The person who walks white, and that speaks straight; the person who hates deceitful exchange for personal gain, that snaps clean his hands from taking this world’s riches, who corks up his ears from hearing bloody (things), who closes his eyes from looking upon evil; He will abide up high”.
