Proverbs 27:1

27:1 Do not boast ¹  about tomorrow; ² 

for you do not know ³  what a day may bring forth.

Proverbs 31:30

31:30 Charm is deceitful ⁴  and beauty is fleeting, ⁵ 

but a woman who fears the Lord ⁶  will be praised.

¹ 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.”

² sn The word “tomorrow” is a metonymy of subject, meaning what will be done tomorrow, or in the future in general.

³ 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).

⁴ tn The first word of the twenty-first line begins with שׁ (shin), the twenty-first letter of the Hebrew alphabet. The graphic distinction between שׁ (shin) and שׂ (sin) had not been made at the time the book of Proverbs was written; that graphic distinction was introduced by the Masoretes, ca. a.d. 1000.

⁵ sn The verse shows that “charm” and “beauty” do not endure as do those qualities that the fear of the Lord produces. Charm is deceitful: One may be disappointed in the character of the one with beauty. Beauty is vain (fleeting as a vapor): Physical appearance will not last. The writer is not saying these are worthless; he is saying there is something infinitely more valuable.

⁶ sn This chapter describes the wise woman as fearing the Lord. It is the fear of the Lord that is the beginning of wisdom – that was the motto of the book (1:7). Psalm 111:10 also repeats that the fear of the Lord is the beginning of wisdom.
