lez'-ing (kazabh "to devise," "to fabricate," hence, "to lie"; occurs but twice in the King James Version (Ps 4:2, the Revised Version (British and American) "falsehood"; 5:6, the Revised Version (British and American) "lies"); the Hebrew word is translated "liars" (Ps 116:11); "lie" or deceive (Job 6:28)): The idea of treachery, lying, and deceit, lies at the root of this word. Joab's conduct is a good illustration of the meaning (2Sa 3:27;20:8-10). InPs 5:6David is referring to the cunning, treachery, and falsehood of his adversaries; compare2Sa 13:28;15:7-9. Doubtless David had a special person in mind as being guilty of "leasing," probably Ahithophel.
