'Diligently' in the Bible

And he saw chariots, horsemen by pairs, a chariot with asses, a chariot with camels; and he hearkened diligently with much heed.

Wherefore do ye spend money for that which is not bread? and your labour for that which satisfieth not? Hearken diligently unto me, and eat ye that which is good, and let your soul delight itself in fatness.
