Charles Ellicott Commentary 2 Corinthians 10:17

"But he that glorieth, let him glory in the Lord." — 2 Corinthians 10:17 (ASV)

He that glorieth, let him glory in the Lord.—Better, He that boasteth, the English translators having again yielded to their besetting weakness for variation. On the general meaning of the phrase, which has been used before, see Note on 1 Corinthians 1:31. Here it has a more special force. “To boast in the Lord” was to boast as in the sight of Christ of that which the boaster considered done, not by himself, but by Christ as dwelling in him.
