2 Corinthians 10:16-18

Young's Literal Translation

¹⁶ in the [places] beyond you to proclaim good news, not in another's line in regard to the things made ready, to boast;

¹⁷ and he who is boasting -- in the Lord let him boast;

¹⁸ for not he who is commending himself is approved, but he whom the Lord doth commend.
