Sufficient unto the day is the evil thereof

"Sufficient unto the day is the evil thereof" is an aphorism which appears in the Sermon on the Mount in the Gospel of Matthew — Matthew 6:34. It also appears in the sermon at the temple in the Book of Mormon- 3 Nephi 13:34. Its meaning is the philosophy that one should live in the present, without a care for tomorrow. The same words, in Hebrew, are used to express the same thought in the Rabbinic Jewish saying dyya l'tzara b'shaata (דיה לצרה בשעתה), "the suffering of the (present) hour is enough for it". It is also similar to the Epicurean advice of writers such as Anacreon and Horace — quid sit futurum cras, fuge quaerere (avoid asking what the future will bring) — but Jesus's point was that God knew the worldly needs of men and so it was more important to seek his kingdom.
