'Cause of the Poor' in the Bible

The righteous considereth the cause of the poor: but the wicked regardeth not to know it.

The king who is a true judge in the cause of the poor, will be safe for ever on the seat of his power.

Lest they being drunken forget the law, and regard not the cause of the poor, and of all such as be in adversity.

Open thy mouth, judge righteously, and plead the cause of the poor and needy.
