'Diligently' in the Bible

Why do you not pardon my disobedience, and take away my iniquity? For now shall I lie down in the dust. You will seek me diligently, but I shall not be."

If you want to seek God diligently, make your supplication to the Almighty.

Hear diligently my speech. Let my declaration be in your ears.

"Listen diligently to my speech. Let this be your consolation.

Behold, as wild donkeys in the desert, they go forth to their work, seeking diligently for food. The wilderness yields them bread for their children.
