13 Go to now, you who say, "Today or tomorrow we shall journey to such a city and spend a year there, and trade and make money,"

14 when all the time you do not know what will happen on the morrow. For what is your life? You are but a mist, appearing for a brief time, and then vanishing.

15 You ought instead to say, "If the Lord wills it, we shall live and do this or that."

16 But now you are glorying in these insolent boastings of yours; all such glorying is evil.

17 So to him who knows how to do right and does not do it, to him it is sin.
