'May' in the Bible

Make search for the Lord, all you quiet ones of the earth, who have done what is right in his eyes; make search for righteousness and a quiet heart: it may be that you will be safely covered in the day of the Lord's wrath.

I said, Certainly you will go in fear of me, and come under my training, so that whatever I may send on her may not be cut off before her eyes: but they got up early and made all their works evil.

For this reason, go on waiting for me, says the Lord, till the day when I come up as a witness: for my purpose is to send for the nations and to get the kingdoms together, so that I may let loose on them my passion, even all my burning wrath: for all the earth will be burned up in the fire of my bitter passion.

For then I will give the people a clean language, so that they may all make prayer to the Lord and be his servants with one mind.
