'Needy' in the Bible

Also in thy skirts hath been found the blood of innocent needy souls, Not by digging have I found them, but upon all these.

They are waxen fat, they shine: yea, they overpass the deeds of the wicked: they judge not the cause, the cause of the fatherless, yet they prosper; and the right of the needy do they not judge.

Sing to the Lord!Praise the Lord,for He rescues the life of the needyfrom the hand of evil people.

He judged the cause of the poor and needy; then it was well with him: was not this to know me? saith the LORD.
