15 Not glorying beyond measure in other men's labours; but having hope of your increasing faith, to be magnified in you according to our rule abundantly;
16 Yea, unto those places that are beyond you, to preach the gospel, not to glory in another man's rule, in those things that are made ready to our hand.
17 But he that glorieth, let him glory in the Lord.
18 For not he who commendeth himself, is approved, but he, whom God commendeth.
