Mateo 6

Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.

Así que, no os congojéis por el día de mañana; que el día de mañana traerá su fatiga: basta al día su afán.

Therefore don’t be anxious for tomorrow, for tomorrow will be anxious for itself. Each day’s own evil is sufficient.
