Matthew Poole and continuators on Psalms 59:6

6. They return at evening : they make a noise like a dog , and go round about the city .

After they have been busie 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 Sam. 19. 11.

Either when he is Hungry and pursuing his prey, and howls for Meat: Or, when he is enraged, and Grins and Snarles where he cannot, or dare not Bite.

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.
