'Good' in the Bible

Your glorying is not good. Know ye not that a little leaven leaveneth the whole lump?

Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.

I say therefore to the unmarried and widows, It is good for them if they abide even as I.

I suppose therefore that this is good for the present distress, I say, that it is good for a man so to be.

Be not deceived: evil communications corrupt good manners.
