13 Go to now, ye that say, To day or to morrow we will go into such a city, and continue (5661) there a year, and buy and sell (5667) , and get gain (5661): 14 Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away. 15 For that ye ought to say, If the Lord will *, we shall live (5661) , and do (5661) this, or that. 16 But now ye rejoice in your boastings: all such rejoicing is evil. 17 Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
