'Necessity' in the Bible

And those who have turned back from following the Lord,And those who have not sought the Lord [as their most important need] or inquired of Him.”

Seek the Lord [search diligently for Him and regard Him as the foremost necessity of your life],All you humble of the landWho have practiced His ordinances and have kept His commandments;Seek righteousness, seek humility [regard them as vital].Perhaps you will be hidden [and pardoned and rescued]In the day of the Lord’s anger.
