19 Know this, my beloved brothers: let every person be quick to hear, slow to speak, slow to anger; 20 for the anger of man does not produce the righteousness of God. – James 1:19-20
3. This may be understood as referring to the disputes and differences that Christians, in those times of trial, were running into among themselves: and so this part of the chapter may be considered without any connection with what goes before. Here we may observe that, whenever matters of difference arise among Christians, each side should be willing to hear the other. People are often stiff in their own opinions because they are not willing to hear what others have to offer against them: whereas we should be swift to hear reason and truth on all sides, and be slow to speak any thing that should prevent this: and, when we do speak, there should be nothing of wrath; for a soft answer turneth away wrath. As this epistle is designed to correct a variety of disorders that existed among Christians, these words, swift to hear, slow to speak, slow to wrath, may be very well interpreted according to this last explication.
