'Helpless' in the Bible

He lurks in ambush in the villages;In hiding places he kills the innocent;He lies in wait for the unfortunate [the unhappy, the poor, the helpless].

He lurks in a hiding place like a lion in his lair;He lies in wait to catch the afflicted;He catches the afflicted when he draws him into his net.

He crushes [his prey] and crouches;And the unfortunate fall by his mighty claws.
