James 4:16
King James Version
“But now ye rejoice in your boastings: all such rejoicing is evil.”
Context
13Go to now, ye that say, To day or to morrow we will go into such a city, and continue there a year, and buy and sell, and get gain:
14Whereas ye know not what on the morrow. For what your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
15For that ye to say, If the Lord will, we shall live, and do this, or that.
16But now ye rejoice in your boastings: all such rejoicing is evil.
17Therefore to him that knoweth to do good, and doeth not, to him it is sin.
