13 Go to now, ye that say, To day or to morrow we will go to such a city, and continue there a year, and traffick, and get gain:14 Who know not what shall be on the morrow; for what is your life? It is a vapour that appeareth for a little time and then vanisheth away:15 Instead of your saying, If the Lord will, we shall both live, and do this or that.16 But now ye glory in your boastings: all such glorying is evil.17 Therefore to him that knoweth to do good and doeth it not, to him it is sin.
