2 Corinthians 10:17

15 Not boasting of things without our measure, that is, of other men’s labours; but having hope, when your faith is increased, that we shall be enlarged by you according to our rule abundantly,

16 To preach the gospel in the regions beyond you, and not to boast in another man’s line of things made ready to our hand.

But he that glorieth, let him glory in the Lord.

18 For not he that commendeth himself is approved, but whom the Lord commendeth.

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