Proverbs 21:11

21:11 When a scorner is punished, the naive ¹  becomes wise;

when a wise person is instructed, ²  he gains knowledge.

Deuteronomy 13:11

13:11 Thus all Israel will hear and be afraid; no longer will they continue to do evil like this among you. ³ 

Deuteronomy 21:21

21:21 Then all the men of his city must stone him to death. In this way you will purge out ⁴  wickedness from among you, and all Israel ⁵  will hear about it and be afraid.

[21:11]  ¹ sn The contrast here is between the simple and the wise. The simple gain wisdom when they see the scorner punished; the wise gains knowledge through instruction. The scorner does not change, but should be punished for the benefit of the simple (e.g., Prov 19:25).

[21:11]  ² tn Heb “in the instructing of the wise.” The construction uses the Hiphil infinitive construct הַשְׂכִּיל (haskil) with a preposition to form a temporal clause (= “when”). The word “wise” (חָכָם, khakham) after it is the subjective genitive. The preposition לְ (lamed) on the form is probably dittography from the ending of the infinitive.

[13:11]  ³ sn Some see in this statement an argument for the deterrent effect of capital punishment (Deut 17:13; 19:20; 21:21).

[21:21]  ⁴ tn The Hebrew term בִּעַרְתָּה (bi’artah), here and elsewhere in such contexts (cf. Deut 13:5; 17:7, 12; 19:19; 21:9), suggests God’s anger which consumes like fire (thus בָעַר, ba’ar, “to burn”). See H. Ringgren, TDOT 2:203-4.

[21:21]  ⁵ tc Some LXX traditions read הַנִּשְׁאָרִים (hannish’arim, “those who remain”) for the MT’s יִשְׂרָאֵל (yisra’el, “Israel”), understandable in light of Deut 19:20. However, the more difficult reading found in the MT is more likely original.
