'May' in the Bible

and replied to the king, “May the king live forever! Why should I not be sad when the city where my ancestors are buried lies in ruins and its gates have been destroyed by fire?”

and answered the king, “If it pleases the king, and if your servant has found favor with you, send me to Judah and to the city where my ancestors are buried, so that I may rebuild it.”

I also shook the folds of my robe and said, “May God likewise shake from his house and property everyone who doesn’t keep this promise. May he be shaken out and have nothing!”The whole assembly said, “Amen,” and they praised the Lord. Then the people did as they had promised.

Then the Levites—Jeshua, Kadmiel, Bani, Hashabneiah, Sherebiah, Hodiah, Shebaniah, and Pethahiah—said, “Stand up. Praise Yahweh your God from everlasting to everlasting.”Praise Your glorious name,and may it be exalted above all blessing and praise.
