Therefore concerning the eating of things sacrificed to idols, we know that no idol is anything in the world, and that there is no other God but one.

Now concerning the collection for the saints, as I commanded the assemblies of Galatia, you do likewise.

Now concerning Apollos, the brother, I strongly urged him to come to you with the brothers; and it was not at all his desire to come now; but he will come when he has an opportunity.
