Psalms 140:1

Deliver me, O LORD, from the evil man: preserve me from the violent man;

The verse is David's prayer for deliverance from the evil man. It may also be turned inward, taking the evil man to mean oneself. That inward reading is a doubtful explanation of the verse. Yet it usefully teaches constant watchfulness against inner evil propensities. It warns of the danger of being misled into sin by one's own weaknesses.
