'May' in the Bible

Though Edom says, We are crushed down but we will come back, building up the waste places; this is what the Lord of armies has said: They may put up buildings, but I will have them pulled down; and they will be named The land of evil-doing, and The people against whom the Lord keeps his wrath for ever.

And now, make request for the grace of God so that he may have mercy on us: this has been your doing: will he give his approval to any of you? says the Lord of armies.

But by whom may the day of his coming be faced? and who may keep his place when he is seen? for he is like the metal-tester's fire and the cleaner's soap.

He will take his seat, testing and cleaning the sons of Levi, burning away the evil from them as from gold and silver; so that they may make offerings to the Lord in righteousness.

Let your tenths come into the store-house so that there may be food in my house, and put me to the test by doing so, says the Lord of armies, and see if I do not make the windows of heaven open and send down such a blessing on you that there is no room for it.

And by him the hearts of fathers will be turned to their children, and the hearts of children to their fathers; for fear that I may come and put the earth under a curse.
