Proverbs 27:1

27:1 Do not boast about tomorrow;

for you do not know what a day may bring forth.


tn The form אַל־תִּתְהַלֵּל (’al-tithallel) is the Hitpael jussive negated; it is from the common verb “to praise,” and so in this setting means “to praise oneself” or “to boast.”

sn The word “tomorrow” is a metonymy of subject, meaning what will be done tomorrow, or in the future in general.

sn The expression “you do not know” balances the presumption of the first line, reminding the disciple of his ignorance and therefore his need for humility (e.g., Matt 6:34; Luke 12:20; Jas 4:13-16).
