'Good' in the Bible

Your boasting is not good. Do ye not know that a little leaven leavens the whole lump?

But concerning the things of which ye have written to me: It is good for a man not to touch a woman;

But I say to the unmarried and to the widows, It is good for them that they remain even as I.

I think then that this is good, on account of the present necessity, that it is good for a man to remain so as he is.

But I have used none of these things. Now I have not written these things that it should be thus in my case; for it were good for me rather to die than that any one should make vain my boast.

On this account many among you are weak and infirm, and a good many are fallen asleep.

Be not deceived: evil communications corrupt good manners.

Now concerning the brother Apollos, I begged him much that he would go to you with the brethren; but it was not at all his will to go now; but he will come when he shall have good opportunity.
