'May' in the Bible

Seek ye Jehovah, all ye meek of the earth, that have kept his ordinances; seek righteousness, seek meekness: it may be ye will be hid in the day of Jehovah's anger.

Therefore wait ye for me, saith Jehovah, until the day that I rise up to the prey; for my determination is to gather the nations, that I may assemble the kingdoms, to pour upon them mine indignation, even 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 of a pure language, that they may all call upon the name of Jehovah, to serve him with one consent.
