'Poor' in the Bible

Behold, this was the iniquity of thy sister Sodom: pride, fulness of bread, and prosperous ease was in her and in her daughters; neither did she strengthen the hand of the poor and needy.

hath wronged the poor and needy, hath taken by robbery, hath not restored the pledge, and hath lifted up his eyes to the idols, hath committed abomination,

that hath withdrawn his hand from the poor, that hath not received interest nor increase, hath executed mine ordinances, hath walked in my statutes; he shall not die for the iniquity of his father, he shall surely live.

The people of the land have used oppression, and exercised robbery; yea, they have vexed the poor and needy, and have oppressed the sojourner wrongfully.
