Proverbs 3:28

3:28 Do not say to your neighbor, “Go! Return tomorrow

and I will give it,” when ¹  you have it with you at the time. ² 

Proverbs 27:1

27:1 Do not boast ³  about tomorrow; ⁴ 

for you do not know ⁵  what a day may bring forth.

[3:28]  ¹ tn Heb “and it is with you.” The prefixed vav introduces a circumstantial clause: “when …”

[3:28]  ² tn The words “at the time” are not in the Hebrew text, but are supplied in the translation for clarity.

[27:1]  ³ 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.”

[27:1]  ⁴ sn The word “tomorrow” is a metonymy of subject, meaning what will be done tomorrow, or in the future in general.

[27:1]  ⁵ 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).
