2 Corinthians 10:17 in the King James Version
But he that glorieth, let him glory in the Lord.
Context
16 so as to preach the Good News even to the parts beyond you, not to boast in what someone else has already done.
17 But “he who boasts, let him boast in the Lord.”
18 For it isn’t he who commends himself who is approved, but whom the Lord commends.
