'May' in the Bible

All things are full of weariness; man may not give their story: the eye has never enough of its seeing, or the ear of its hearing.

That which is bent may not be made straight, and that which is not there may not be numbered.

And I went again in search of wisdom and of foolish ways. What may the man do who comes after the king? The thing which he has done before.

Who may take food or have pleasure without him?

I am certain that whatever God does will be for ever. No addition may be made to it, nothing may be taken from it; and God has done it so that man may be in fear before him.

I said in my heart, It is because of the sons of men, so that God may put them to the test and that they may see themselves as beasts.

So again, if two are sleeping together they are warm, but how may one be warm by himself?

Let not your mouth make your flesh do evil. And say not before the angel, It was an error. So that God may not be angry with your words and put an end to the work of your hands.

As he came from his mother at birth, so does he go again; he gets from his work no reward which he may take away in his hand.

In the day of wealth have joy, but in the day of evil take thought: God has put the one against the other, so that man may not be certain what will be after him.

Far off is true existence, and very deep; who may have knowledge of it?

The word of a king has authority; and who may say to him, What is this you are doing?

Then I saw all the work of God, and that man may not get knowledge of the work which is done under the sun; because, if a man gives hard work to the search he will not get knowledge, and even if the wise man seems to be coming to the end of his search, still he will be without knowledge.

All this I took to heart, and my heart saw it all: that the upright and the wise and their works are in the hand of God; and men may not be certain if it will be love or hate; all is to no purpose before them.

If the wrath of the ruler is against you, keep in your place; in him who keeps quiet even great sins may be overlooked.

But even if a man's life is long and he has joy in all his years, let him keep in mind the dark days, because they will be great in number. Whatever may come is to no purpose.
