'Keep' in the Bible

So then, brothers, be strong in purpose, and keep the teaching which has been given to you by word or by letter from us.

But the Lord is true, who will give you strength and keep you safe from evil.

Now we give you orders, brothers, in the name of our Lord Jesus Christ, to keep away from all those whose behaviour is not well ordered and in harmony with the teaching which they had from us.

And if any man does not give attention to what we have said in this letter, take note of that man, and keep away from him, so that he may be shamed.
