Psalms 59:6

6. They return at evening The poetical account, which here gives a deeper insight than the narrative in 1 Samuel 19:11-16, speaks of a succession of nights. They not only patrolled the city, (see Psalms 59:3,) but had now closely beset his house.

They make a noise like a dog The half wild, gaunt, starved dogs of the East are scarcely less ferocious, and more disgusting, than wolves. They go in packs, and at night their howling, barking, yelping, and growling are as frightful as they are discordant. See on Psalms 22:16
