'May' in the Bible

And they said {to one another}, "Come, let us cast lots so that we may know on whose account this disaster [has come] on us!" And they cast lots, and the lot fell on Jonah.

So they said to him, "What shall we do to you so that the sea may quiet down for us?" because the sea {was growing more and more tempestuous}.

And he said to them, "Pick me up and hurl me into the sea so that the sea may quiet down for you, because I know that on account of me this great storm [has come] upon you all."

Who knows? God may relent and change his mind and turn {from his blazing anger} {so that} we will not perish."
