'May' in the Bible

Seek Jehovah, all ye meek of the land, who have performed his ordinance; seek righteousness, seek meekness: it may be ye shall be hid in the day of Jehovah's anger.

I said, Only fear me, receive correction; so her dwelling shall not be cut off, howsoever I may punish her. But they rose early, they corrupted all their doings.

Therefore wait ye for me, saith Jehovah, until the day that I rise up to the prey; for my determination is to assemble the nations, that I may gather the kingdoms together, to pour upon them mine indignation, all my fierce anger: for all the earth shall be devoured with the fire of my jealousy.

For then will I turn to the peoples a pure language, that they may all call upon the name of Jehovah, to serve him with one consent.
