2 Corinthians 10:18 ASV

¹⁶  so as to preach the gospel even unto the parts beyond you, `and' not to glory in another's province in regard of things ready to our hand.

¹⁷  But he that glorieth, let him glory in the Lord.

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