'Diligent' in the Bible

Poor is he who is working -- a slothful hand, And the hand of the diligent maketh rich.

The hand of the diligent ruleth, And slothfulness becometh tributary.

The slothful roasteth not his hunting, And the wealth of a diligent man is precious.

The soul of the slothful is desiring, and hath not. And the soul of the diligent is made fat.

The purposes of the diligent are only to advantage, And of every hasty one, only to want.
