Psalms 59:6

They return at evening, after they have been busy all day, either in plotting against me, or in hunting after me. In the evening, when they should compose themselves to rest, they return to their old trade of watching for me which they did at this time all the night long, 1 Samuel 19:11. They make a noise like a dog; either when he is hungry and pursuing his prey, and howls for meat; or when he is enraged, and grins and snarls where he cannot or dare not bite. And go round about the city: when they did not find him in his own house, they sought for him in other houses and parts of the city, where they supposed him to lurk.
