Adam Clarke on Psalms 10:8

He sitteth in the lurking places - In this and the following verse there appears to be an allusion to espionage, or setting of spies on a man's conduct; or to the conduct of an assassin or private murderer. He sitteth in lurking places - in secret places; his eyes - spies - are privily set; he lieth in wait secretly: he doth catch the poor, when he draweth him into his net. He is like a hunter that lays his traps and gins, digs his pits, sets his nets; and when the prey falls into them, he destroys its life.
