​¹¹Do not speak evil against one another, brothers and sisters. Whoever speaks evil against another or judges another, speaks evil against the law and judges the law; but if you judge the law, you are not a doer of the law but a judge. ¹²There is one lawgiver and judge who is able to save and to destroy. So who, then, are you to judge your neighbor?

¹³Come now, you who say, “Today or tomorrow we will go to such and such a town and spend a year there, doing business and making money.” ¹⁴Yet you do not even know what tomorrow will bring. What is your life? For you are a mist that appears for a little while and then vanishes. ¹⁵Instead you ought to say, “If the Lord wishes, we will live and do this or that.” ¹⁶As it is, you boast in your arrogance; all such boasting is evil. ¹⁷Anyone, then, who knows the right thing to do and fails to do it, commits sin.
