'Profit' in the Bible

For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.

So the law which went before is put on one side, because it was feeble and without profit.

For they verily for a few days chastened us after their own pleasure; but he for our profit, that we might be partakers of his holiness.

Do not be carried away by diverse and strange teachings; for it is good for the heart to be established and strengthened by grace and not by foods [rules of diet and ritualistic meals], which bring no benefit or spiritual growth to those who observe them.

Give ear to those who are rulers over you, and do as they say: for they keep watch over your souls, ready to give an account of them; let them be able to do this with joy and not with grief, because that would be of no profit to you.

But, brothers, take kindly the words which I have said for your profit; for I have not sent you a long letter.
