13. Come now, you who say, Today or tomorrow we will go into such and such a city and spend a year there and carry on our business and make money.
14. Yet you do not know [the least thing] about what may happen tomorrow. What is the nature of your life? You are [really] but a wisp of vapor (a puff of smoke, a mist) that is visible for a little while and then disappears [into thin air].
15. You ought instead to say, If the Lord is willing, we shall live and we shall do this or that [thing].
16. But as it is, you boast [falsely] in your presumption and your self-conceit. All such boasting is wrong.
17. So any person who knows what is right to do but does not do it, to him it is sin.
