MKJV(i)
13 But we will not boast beyond measure, but according to the measure of the rule which the God of measure distributed to us, to reach even to you.
14 For we do not overstretch ourselves as though not reaching to you. For we also came to you in the gospel of Christ;
15 not boasting beyond measure in the labors of others, but having hope that the growing faith among you will be increased according to our rule, to overflowing;
16 to preach the gospel in that beyond you, and not to boast in another's rule in things made ready.
17 But he who glories, let him glory in the Lord.
18 For not he who commends himself is approved, but he whom the Lord commends.
