9 In my letter I said to you that you were not to keep company with those who go after the desires of the flesh;
9
I wrote to you in my letter not to associate with sexually immoral people—
10 But I had not in mind the sinners who are outside the church, or those who have a desire for and take the property of others, or those who give worship to images; for it is not possible to keep away from such people without going out of the world completely:
10
not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world.
