2 Corinthians 10:17

15 Neither do we boast beyond our limits in the labors of others. But we hope that as your faith increases, our area of influence among you will greatly increase as well,

16 so that we can preach the gospel in the regions beyond you. Then we will not be boasting in the work already done in another man’s territory.

Rather, “Let him who boasts boast in the Lord.”

18 For it is not the one who commends himself who is approved, but the one whom the Lord commends.

Do read the surrounding verses too, because the context often says more than a single verse.
