I now want to reply to the matter of idolatrous sacrifices [which you wrote to me about]. We know that we all possess knowledge. [Note: This may be a statement posed to Paul by the Corinthians, who seemed quite preoccupied with "knowledge"]. Knowledge [only] makes people arrogant, while love builds them up [spiritually].

For the person who speaks in a language [supernaturally] does not speak to people, but to God, for no one can understand him [i.e., unless there is an interpreter or it is the person's native language]; he speaks [previously] unrevealed truths under the influence of the Holy Spirit [or "in his spirit"]. [Note: For a correct understanding of this chapter, it must be kept in mind that Paul is addressing a misuse ofthe gift of speaking in languages supernaturally. The Corinthians were doing this in the wrong way and for the wrong purpose].

For they cheered me up, as they have cheered [or, will cheer] you up [also]. [Note: How these three men did this for Paul and the Corinthians is not known]. You should give recognition to such men.

Using the unearned favor shown to me by God [Note: Paul here probably refers to his apostleship and its attending spiritual gifts], as an expert building contractor, I laid the foundation [i.e., in starting the Corinthian church], and someone else is building on it [i.e., Apollos. See verse 6].
