Not to be taken lightly

2 Hearken, O ye who have given your names to go forth to proclaim my gospel, and to prune my vineyard.

3 Behold, I say unto you that it is my will that you should go forth and not tarry, neither be idle but labor with your might—

4 Lifting up your voices as with the sound of a trump, proclaiming the truth according to the revelations and commandments which I have given you.
