13 How foolish it is to say, Today or tomorrow we will go into this town, and be there for a year and do business there and get wealth:
14 When you are not certain what will take place tomorrow. What is your life? It is a mist, which is seen for a little time and then is gone.
15 But the right thing to say would be, If it is the Lord's pleasure and if we are still living, we will do this and that.
16 But now you go on glorying in your pride: and all such glorying is evil.
17 The man who has knowledge of how to do good and does not do it, to him it is sin.
