13 Come now, you that say, Today or tomorrow we will go into such a city, and continue there a year, and buy and sell, and get gain:
14 Whereas you know not what shall be tomorrow. For what is your life? It is even a vapor, that appears for a little time, and then vanishes away.
15 For you ought to say, If the Lord wills, we shall live, and do this, or that.
16 But now you rejoice in your boastings: all such rejoicing is evil.
17 Therefore to him that knows to do good, and does it not, to him it is sin.
