“Boast not thyself of to morrow; for thou knowest not what a day may bring forth.”
King James Version (KJV)

Read Full Chapter →Every year some plan collapses in a way nobody saw coming, and every year we make new plans with the same confidence. Proverbs 27 opens by naming that habit. The correction it offers is modest and precise: keep making plans, and stop announcing them as though the day were already ours to spend.
Tomorrow belongs to God, so announcing what we will accomplish in it overreaches. The proverb asks for humility about a day whose contents remain entirely unknown to us.
The Context of Proverbs 27:1
Chapter 27 collects sayings about self-knowledge, friendship, and stewardship. Verse 1 sits at the head, and verse 2 follows with a matching restraint on self-praise: let another praise you rather than your own mouth. That pairing sets the tone. Later verses describe faithful wounds from a friend, iron sharpening iron, and water reflecting a face the way one heart answers another. The chapter closes with a long section on tending flocks and herds, noting that riches do not last forever, which returns to the same theme of a future nobody owns.
What Does Proverbs 27:1 Mean?
The verb is 'boast,' and it targets speech about the future rather than the act of preparing for it. To boast of tomorrow is to talk about a day as though its contents were already in hand. The reason follows: 'thou knowest not what a day may bring forth.' The phrase 'bring forth' is birth language, picturing a day as pregnant with events nobody has yet seen. Notice how short the horizon is. The proverb declines to say a decade or a year; it says a day. Whatever margin of confidence we imagine we have, the sage measures it in a single sunrise.
Pairing this line with verse 2 shows what the sage is after. Boasting about tomorrow and praising oneself today are the same error pointed in two directions, since both claim credit for something outside our control. Proverbs consistently keeps the future in God's hands while asking us to work hard in the present. The book that warns against presuming on tomorrow is the same book that tells us to store food in summer and know the state of our flocks. Ignorance about the future turns out to be an argument for diligence today, and the closing verses of this chapter make exactly that move.
Jesus told a story that could serve as this proverb's illustration. A farmer with a bumper harvest plans bigger barns and tells himself he has goods laid up for many years, and God says his soul will be required of him that very night. The parable adds a diagnosis the proverb leaves implicit: the man had spoken to himself about years he never possessed. James later supplies the practical correction, teaching believers to say that if the Lord wills they will live and do this or that. Christ himself met each day as it came, which is the posture these texts commend.
Proverbs 27:1 in the Original Language
yalad (יָלַד), 'bring forth' -- to give birth or bear a child. Applying the verb to a day makes tomorrow something carrying events still hidden, so the proverb's caution rests on a picture of something alive and unseen rather than on mere uncertainty.

Where Proverbs 27:1 Echoes in Scripture
Luke 12:20 supplies the sharpest commentary Scripture offers on this proverb. God addresses the prosperous farmer as a fool and tells him his soul is required of him that night, asking whose the stored goods will then be. The man's error was verbal before it was financial; he had narrated a future into existence in his own hearing. Jesus attaches a moral about being rich toward God, which turns the proverb from a caution about speech into a question about where a life is invested.
How to Apply Proverbs 27:1 Today
Small changes in how we speak can carry this proverb into daily life. Saying we intend to do something, or hope to, keeps the sentence honest without draining the ambition out of it. Beyond speech, the verse argues for keeping short accounts. Apologies deferred to a better moment, calls postponed until things settle, and thanks we mean to give someday are all bets placed on a day we have never seen. Finishing one of those today is a practical way of taking the proverb seriously.
Reflection & Prayer
What have we been saving for a tomorrow we assumed would arrive? Choose one item and handle it before the day ends. A prayer: Father, tomorrow is Yours and I keep speaking as though it were mine. Teach me to plan without presuming. Give me courage for the words I have been postponing, and a quiet heart about the rest. Amen.
