Psalms 59:15 - Ellicott's Commentary On The Whole Bible

Let them wander. — This verse is variously understood. The margin gives the rendering of most modern scholars; but what does it mean by “They will pass the night”? To say they will not go away unsatisfied seems poor. Ewald’s conjecture, “They will satisfy themselves forsooth, and remain,” i.e., die, seems strained. The slightest change in the vowel-points gives the interpretation adopted by the LXX., Vulg., Jerome, Luther, &c: “If not satisfied they will growl,” which admirably suits the context.
