'May' in the Bible

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.

“Then I will give to the peoples [clear and pure speech from] purified lips [which reflect their purified hearts],That all of them may call on the name of the Lord,To serve Him shoulder to shoulder (united).
