'May' in the Bible

Holding fast the faithful word as he hath been taught, that he may be able by sound doctrine both to exhort and to convince the gainsayers.

This witness is true. Wherefore rebuke them sharply, that they may be sound in the faith;

That they may teach the young women to be sober, to love their husbands, to love their children,

Sound speech, that cannot be condemned; that he that is of the contrary part may be ashamed, having no evil thing to say of you.

Not purloining, but shewing all good fidelity; that they may adorn the doctrine of God our Saviour in all things.
