4 13 Come now, you who say, "Today or tomorrow we will go into such and such a town and spend a year there and trade and get gain"; 4 14 whereas you do not know about tomorrow. What is your life? For you are a mist that appears for a little time and then vanishes. 4 15 Instead you ought to say, "If the Lord wills, we shall live and we shall do this or that." 4 16 As it is, you boast in your arrogance. All such boasting is evil. 4 17 Whoever knows what is right to do and fails to do it, for him it is sin.
