11 Do not speak evil of one another, brothers. The one who speaks evil of a brother or judges his brother speaks evil of the law and judges the law. But if you judge the law, you are not a doer of the law but a judge of the law.
12 There is one lawgiver and judge who is able to save and to destroy. But who are you to judge your neighbor?
13 Come now, you who say, “Today or tomorrow we will travel to such and such a city and spend a year there, and carry on business and make a profit,”
14 you who do not know what will happen tomorrow, what your life will be like. For you are a smoky vapor that appears for a short time and then disappears.
15 Instead you should say, “If the Lord wills, we will live and do this or that.”
16 But now you boast in your arrogance. All such boasting is evil.
17 Therefore, to the one who knows to do good and does not do it, to him it is sin.
