That in every thing - In every respect, or in regard to all the favors conferred on any of his people. You have been distinguished by him in all those respects in which he blesses his own children.
Ye are enriched by him; - compare the note at Romans 2:4. The meaning of this expression is, "you abound in these things; they are conferred abundantly upon you." By the use of this word, the apostle intends doubtless to denote "the fact" that these blessings had been conferred on them abundantly; and also that this was a "valuable endowment," so as to be properly called "a treasure." The mercies of God are not only conferred abundantly on his people, but they are a bestowment of inestimable value; compare 2-Corinthians 6:10.
In all utterance - With the power of speaking various languages ἐν παντὶ λόγῳ en panti logō. That this power was conferred on the church at Corinth, and that it was highly valued by them, is evident from 1 Cor. 14; compare 2-Corinthians 8:7. The power of speaking those languages the apostle regarded as a subject of thanksgiving, as it was a proof of the divine favor to them; see 1-Corinthians 14:5, 1-Corinthians 14:22, 1-Corinthians 14:39.
And in all knowledge - In the knowledge of divine truth. They had understood the doctrines which they had heard, and had intelligently embraced them. This was not true of all of them, but it was of the body of the church; and the hearty commendation and thanksgiving of the apostle for these favors, laid the foundation for the remarks which he had subsequently to make, and would tend to conciliate their minds, and dispose them to listen attentively, even to the language of reproof.

Ye are enriched - ye abound - in all utterance - Εν παντι λογῳ, In all doctrine; for so the word should certainly be translated and understood. All the truths of God relative to their salvation had been explicitly declared to them; and they had all knowledge; so that they perfectly comprehended the doctrines which they had heard.

That in every thing ye are enriched by him, (8) in (d) all utterance, and [in] all knowledge;
(8) He refers to that by name which they abused the most.
(d) Seeing that while we live here we know but in part, and prophesy in part, this word "all" must be limited by the present state of the faithful: and by "utterance" he does not mean a vain kind of babbling, but the gift of holy eloquence, which the Corinthians abused.

That in everything ye are enriched by him,.... This is still a continuation of the thanksgiving for this church, that they were "enriched", or plentifully and abundantly provided for by Christ, with all grace, with all the riches of grace; with his own unsearchable riches, of which they were made partakers, and the riches of glory, to which they were entitled by him; and all which come to them through his poverty, which makes his grace in the donation of these riches the more illustrious: and particularly the apostle is thankful, that they were enriched by Christ
in all utterance, and in all knowledge; that not only they had the knowledge of the truths and doctrines of the Gospel, concerning the person, offices, grace, and righteousness of Christ in the theory of them, or a speculative notion of them; but for the most part had a spiritual experimental knowledge of these things; and many of them had such large gifts of knowledge, elocution, and utterance, that they were richly qualified to preach the Gospel to others; nay, even had the extraordinary gifts of the Spirit, so as to speak with divers tongues, as the Spirit gave them utterance.

utterance--ALFORD from MENOCHIUS translates, "doctrine." Ye are rich in preachers or the preaching of the word, and rich in knowledge or apprehension of it: literally "(the) word (preached)." English Version (as in 2-Corinthians 8:7) is better: for Paul, purposing presently to dwell on the abuse of the two gifts on which the Corinthians most prided themselves, utterance (speech) and knowledge (1-Corinthians 1:20; 1-Corinthians 3:18; 1-Corinthians 4:19; 1Co. 13:1-14:40), previously gains their goodwill by congratulating them on having those gifts.

In all utterance and knowledge - Of divine things. These gifts the Corinthians particularly admired. Therefore this congratulation naturally tended to soften their spirits, and I make way for the reproofs which follow.
