'Justice for the Poor' in the Bible

"You are not to pervert justice for the poor among you in their lawsuits.

I know [with confidence] that the Lord will maintain the cause of the afflicted,And [will secure] justice for the poor.

The righteous care about justice for the poor. The wicked aren't concerned about knowledge.

Open your mouth, judge righteously,And administer justice for the afflicted and needy.
