'Diligent' in the Bible

Now the man Jeroboam [was] a man of ability, and Solomon saw that the young man {was a diligent worker}, so he appointed him over all of the forced labor for the house of Joseph.

A slack hand causes poverty, but the hand of the diligent enriches.

The hand of the diligent ones will rule, but the lazy will belong to forced labor.

The plans of the diligent only [lead] to abundance, but all who are hasty, only to want.
