'May' in the Bible

For her wounds may not be made well: for it has come even to Judah, stretching up to the doorway of my people, even to Jerusalem.

And the rest of Jacob will be among the mass of peoples like dew from the Lord, like showers on the grass, which may not be kept back by man, or be waiting for the sons of men.

O my people, keep in mind now what was designed by Balak, king of Moab, and the answer which Balaam, son of Beor, gave him; the events, from Shittim to Gilgal, so that you may be certain of the upright acts of the Lord.
