Proverbs 6:15

6:15 Therefore, his disaster will come suddenly;

in an instant ¹  he will be broken, and there will be no remedy.

Proverbs 29:1

29:1 The one who stiffens his neck ²  after numerous rebukes ³ 

will suddenly be destroyed ⁴  without remedy. ⁵ 

[6:15]  ¹ tn This word is a substantive that is used here as an adverbial accusative – with suddenness, at an instant.

[29:1]  ² tn The idiom “to harden the neck” (מַקְשֶׁה־עֹרֶף, maqsheh-’oref) is the idea of resisting the rebukes and persisting in obstinacy (e.g., Exod 32:9). The opposite of a “stiff neck” would be the bending back, i.e., submission.

[29:1]  ³ tn The Hebrew construction is אִישׁ תּוֹכָחוֹת (’ish tokhakhot, “a man of rebukes”), meaning “a man who has (or receives) many rebukes.” This describes a person who is deserving of punishment and who has been given many warnings. The text says, then, “a man of rebukes hardening himself.”

[29:1]  ⁴ sn The stubborn person refuses to listen; he will suddenly be destroyed when the calamity strikes (e.g., Prov 6:15; 13:18; 15:10).

[29:1]  ⁵ tn Or “healing” (NRSV).
