Matthew 6:34
Therefore don't be anxious for tomorrow, for tomorrow will be anxious for itself. Each day's own evil is sufficient.

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.

What Matthew 6:34 means
At the close of the Sermon on the Mount, Jesus tells worried listeners to stop being pulled apart by tomorrow. Each day brings enough of its own trouble, and the security they keep reaching for rests with a Father who already knows what they need.
Matthew 6:34 is the last line of a long passage about worry in the Sermon on the Mount, Jesus's best-known stretch of teaching. Just before it, he has pointed the crowd to the birds, which do not store up harvests, and the wildflowers, which outshine kings without trying, and told them to stop being consumed by what they will eat, drink, and wear. Verse 34 lands the point: do not pile tomorrow's worry on top of today's.
The setting matters. Jesus was speaking to ordinary people in Roman-occupied Galilee, many of them day-laborers and subsistence farmers living close to the edge, for whom "what will we eat tomorrow" was not a figure of speech. This is not a lecture telling the comfortable to relax. It is a word to people who genuinely did not know whether tomorrow's bread was secure, telling them they were not built to carry tomorrow's fear today, because the God who feeds the birds already knows what they need.
Two things get lost in English. The word for "worry" is the Greek merimnaō, which carries the sense of a mind pulled apart, divided, torn in several directions at once. Its target is the anxious fracturing of the self, not the work of careful planning. And the word older translations render as "evil" (the King James reads "sufficient unto the day is the evil thereof") is kakia, which here means trouble or hardship rather than moral wickedness. The line is not weighing sin. It is measuring how much difficulty a single day can already hold.
