'Poor' in the Bible

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

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

who has withdrawn his hand from the poor, who has not received interest nor increase, has executed my ordinances, has walked in my statutes; he shall not die for the iniquity of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; yes, they have troubled the poor and needy, and have oppressed the foreigner wrongfully.
