13 Come now, you who say, »Today or tomorrow we will go to such and such a city, and spend a year there and engage in business and make a profit.«

14 Yet you do not know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes.

15 Instead, you ought to say, »If the Lord wills, we will live and do this or that.«

16 As it is, you boast in your arrogance. All such boasting is evil.

17 Therefore, to one who knows the right thing to do and does not do it, to him it is sin.
