'Poor' in the Bible

'If thou dost lend My poor people with thee money, thou art not to him as a usurer; thou dost not lay on him usury;

and a poor man thou dost not honour in his strife.

the rich doth not multiply, and the poor doth not diminish from the half-shekel, to give the heave-offering of Jehovah, to make atonement for your souls.
