Their mouths are filled with cursing and deceit and oppression; under their tongues are mischief and iniquity. They sit in ambush in the villages; in hiding-places they murder the innocent. Their eyes stealthily watch for the helpless; they lurk in secret like a lion in its cover; they lurk that they may seize the poor; they seize the poor and drag them off in their net. They stoop, they crouch, and the helpless fall by their might.They think in their heart, ‘God has forgotten, he has hidden his face, he will never see it.’ (Psalm 10: 7-11)

The psalms feature the wicked nearly as much as God. There are many Hebrew words for wicked. What is translated above as iniquity is often rendered as wickedness.

The source word is 'aven. This originally meant to pant as when doing hard labor. There is the suggestion of panting and working in vain.

Earlier in this psalm it is written the wicked person's way of life is always chuwl (pronounced cool). This is whirling, twisting, and writhing. There is great exertion, but very little progress.

The psalmist too often envies the wicked. He perceives they enjoy their success. Their plots often succeed. But there is no joy. There is no end or fulfillment in the work of the wicked.

The wicked are twirling and whirling all alone. Joy is found in dancing with God.
