13. Come now, you who say, “Today or tomorrow we will go to such and such a town and spend a year there and engage in business and make a profit.”
14. Yet you do not know what your life will be like tomorrow. What is your life? For you are a vapor that appears for a little while and then vanishes.
15. Instead you ought to say, “If the Lord wills, we will live and also do this or that.”
16. But now you boast in your arrogance. All such boasting is evil.
17. Therefore whoever knows the right thing to do and does not do it—for him it is sin.
