2 Corinthians
King James Version (KJV)

“For we are not as many, which corrupt the word of God: but as of sincerity, but as of God, in the sight of God speak we in Christ.”
King James Version (KJV)
2:17 For we are not as many, who adulterate the word of God - Like those vintners (so the Greek word implies) who mix their wines with baser liquors. But as of sincerity - Without any mixture. But as from God - This rises higher still; transmitting his pure word, not our own. In the sight of God - Whom we regard as always present, and noting every word of our tongue. Speak we - The tongue is ours, but the power is God's. In Christ - Words which he gives, approves, and blesses.
2Co 2:17 We are not as many, who corrupt the word of God. The Greek city figure is taken from the tavern-keepers who adulterate the wine they offer for sale. There were those at Corinth, Judaizing teachers, who adulterated the gospel with ingredients of Judaism. These are the "false brethren" (2Co 11:26) with whom his whole ministry was a struggle. See also Ga 2:4. But as of sincerity, but as of God. On the contrary, he and his fellow-preachers spoke the words of genuine sincerity and with a sense of responsibility to God.
