'Ought' in the Bible

And you are proud and arrogant! You should have mourned in shame so that the man who has done this [disgraceful] thing would be removed from your fellowship!

and not certainly with the whoremongers of this world, or with the covetous, or extortioners, or idolaters, seeing ye ought then to go forth out of the world --

But what I meant was that you were not to associate with any one bearing the name of "brother," if he was addicted to fornication or avarice or idol-worship or abusive language or hard-drinking or greed of gain. With such a man you ought not even to eat.

If a man thinks he is not behaving properly toward his virgin, and if his passion is so strong that he feels he ought to marry her, let him do what he wants; he isn't sinning. Let them get married.

And if any man think that he knoweth any thing, he knoweth nothing yet as he ought to know.

Or isn’t He really saying it for us? Yes, this is written for us, because he who plows ought to plow in hope, and he who threshes should do so in hope of sharing the crop.

For a man indeed ought not to cover his head, forasmuch as he is the image and glory of God: but the woman is the glory of the man.

For this cause ought the woman to have power on her head because of the angels.

Become sober-minded as you ought, and stop sinning; for some have no knowledge of God. I speak this to your shame.
