9. Begin to lament, to mourn, to weep. Let your laughter be turned into mourning and your joy into dejection.
10. Humble yourselves before the Lord and he will exalt you.
11. Do not speak evil of one another, brothers. Whoever speaks evil of a brother or judges his brother speaks evil of the law and judges the law. If you judge the law, you are not a doer of the law but a judge.
12. There is one lawgiver and judge who is able to save or to destroy. Who then are you to judge your neighbor?
13. Come now, you who say, “Today or tomorrow we shall go into such and such a town, spend a year there doing business, and make a profit”—
14. you have no idea what your life will be like tomorrow. You are a puff of smoke that appears briefly and then disappears.
15. Instead you should say, “If the Lord wills it, we shall live to do this or that.”
16. But now you are boasting in your arrogance. All such boasting is evil.
17. So for one who knows the right thing to do and does not do it, it is a sin.
