James 1:19

19 This you know, my beloved brethren. But everyone must be quick to hear, slow to speak and slow to anger;

James 3:1

1 Let not many of you become teachers, my brethren, knowing that as such we will incur a stricter judgment.

James 4:4

4 You adulteresses, do you not know that friendship with the world is hostility toward God? Therefore whoever wishes to be a friend of the world makes himself an enemy of God.
