Adam Clarke on Psalms 59:14

At evening let them return - He had mentioned before, Psa 59:6 that these persons came like beasts of prey round the city striving to get in, that they might take possession. Now, being fully assured of God's protection and that they shall soon be made a public example, he says, Let them return and make a noise like a dog, etc., like dogs, jackals, and other famished creatures, who come howling about the city-walls for something to eat, and wander up and down for meat, grumbling because they are not satisfied, Psa 59:15. Nehemiah had made up all the breaches; and had the city guarded so well day and night, by watches who continually relieved each other, that there was no longer any fear of being taken by surprise: and now they must feel like the hungry beasts who were disappointed of their prey.
