The malignity and deceit (Psa 140:3) of such are followed by acts combining cunning, fraud, and violence (compare Pro 1:11, Pro 1:18), aptly illustrated by the habits of the lion, and of hunters taking their prey. "Poor," in Psa 10:8, Psa 10:10, Psa 10:14, represents a word peculiar to this Psalm, meaning the sad or sorrowful; in Psa 10:9, as usual, it means the pious or meek sufferer.
