'May' in the Bible

May grace, mercy, and peace be with us from God the Father, and from Jesus Christ, the Son of the Father, in all true love.

and now I beseech thee, Kyria, not as writing to thee a new command, but which we had from the beginning, that we may love one another,

and this is the love, that we may walk according to His commands; this is the command, even as ye did hear from the beginning, that in it ye may walk,

Watch yourselves so you don’t lose what we have worked for, but that you may receive a full reward.

Having many things to write unto you, I would not write with paper and ink: but I trust to come unto you, and speak face to face, that our joy may be full.
