'May' in the Bible

Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:

That I may make it manifest, as I ought to speak.

Let your speech be alway with grace, seasoned with salt, that ye may know how ye ought to answer every man.

Epaphras, who is one of you, a servant of Christ, saluteth you, always labouring fervently for you in prayers, that ye may stand perfect and complete in all the will of God.
