Therefore, take ye no thought for the morrow, for what ye shall eat, or what ye shall drink, or wherewithal ye shall be clothed. For, consider the lilies of the field, how they grow, they toil not, neither do they spin; and the kingdoms of the world, in all their glory, are not arrayed like one of these. For your Father, who is in heaven, knoweth that you have need of all these things. Therefore, let the morrow take thought for the things of itself.
Doctrine and Covenants 84:81-84
