James 3:9-13

By it we bless God, &c. Such different effects from the same cause, as of blessing God, and cursing men, created to the likeness of God, seem contrary to the ordinary course of nature; from a fountain from the same source doth not send forth both sweet and bitter streams. --- Who is a wise man, and endued with knowledge among you? &c. This seems to be connected with the admonition given at the beginning of the chapter, be not many masters; let none pretend to this but who have wisdom and knowledge, which also may be known by their prudent and mild conversation.
