Psalms 10:14-15

14 But you yourself have been watching trouble and grief, observing it in order to take the matter into your hands. The helpless one is entrusting himself to you; you are a helper of the fatherless. 15 Break the arm of the wicked, evil person, until you look for his wickedness, but find it no more.

The psalmist reflects on God as carefully monitoring the crimes committed against the poor and helpless. He calls on God to act against this powerful criminal by punishing him. The broken arm prevents further acts of violence. He asks the Lord to keep pursuing these criminals until they are all caught— until there is no one left to pursue. Rid the land of the exploitation.
