'Poor and Needy' in the Bible

The unjust let loose the sword, and they bent their bow; they cast down the poor and needy, to slaughter the upright of way.

And I am poor and needy, Jehovah will think upon me: thou my help and my deliverer; thou will not delay, O my God.

And I am poor and needy: O God, hasten to me, my help and my deliverer; thou, O Jehovah, wilt not delay.

Deliver the poor and needy one: take away out of the hand of the unjust

A prayer to David. Incline, O Jehovah, thine ear: answer me, for I am poor and needy.

Because he remembered not to do mercy, and he will pursue the poor and needy man to slay the dejected of heart.

For poor and needy am I, and my heart wounded in my midst.
