Charles Ellicott Commentary 2 Corinthians 9:13

"seeing that through the proving [of you] by this ministration they glorify God for the obedience of your confession unto the gospel of Christ, and for the liberality of [your] contribution unto them and unto all;" — 2 Corinthians 9:13 (ASV)

Whiles by the experiment of this ministration they glorify God.—The construction of the Greek sentence is again that of a participle which has no direct grammatical connection with what precedes, but the English version sufficiently expresses the meaning. Test would, perhaps, be a better word than “experiment.” The word is the same as that rendered, with a needless variation, “experience” in Romans 5:4, “trial” in 2 Corinthians 8:2, “proof” in 2 Corinthians 13:3.

Your professed subjection.—The English version makes the not infrequent mistake of merging the genitive in a somewhat weak adjective. Literally, in your obedience to the confession of faith. The latter noun is used in this sense in 1 Timothy 6:12–13; Hebrews 3:1; Hebrews 4:14. The word seems to have acquired a half-technical significance, like that which attaches to “faith” and “religion” used objectively.

For your liberal distribution.—The construction is the same as in the previous clause: for the liberality of your contribution.
