'Needy' in the Bible

They are become fat, they shine, yea, they surpass in deeds of wickedness; they judge not the cause, the cause of the fatherless, and they prosper; and the right of the needy do they not adjudge.

Sing ye unto Jehovah, praise Jehovah, for he hath delivered the soul of the needy from the hand of evildoers.

He judged the cause of the poor and needy; then it was well. Was not this to know me? saith Jehovah.
