Proverbs 29:7

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

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

The righteous taketh knowledge of the cause of the poor; The wicked hath not understanding to know `it'.

The righteous knoweth the plea of the poor, The wicked understandeth not knowledge.

The righteous consider the cause of the poor, but the wicked have no regard for such concerns.
