Proverbs 4:16

4:16 For they cannot sleep unless they cause harm; ¹ 

they are robbed of sleep ²  until they make someone stumble. ³ 

Proverbs 20:11

20:11 Even a young man ⁴  is known ⁵  by his actions,

whether his activity is pure and whether it is right. ⁶ 

Proverbs 25:21

25:21 If your enemy is hungry, give him food to eat,

and if he is thirsty, give him water to drink,

[4:16]  ¹ sn The verb is רָעַע (ra’a’), which means “to do evil; to harm.” The verse is using the figure of hyperbole to stress the preoccupation of some people with causing trouble. R. L. Alden says, “How sick to find peace only at the price of another man’s misfortune” (Proverbs, 47).

[4:16]  ² sn Heb “their sleep is robbed/seized”; these expressions are metonymical for their restlessness in plotting evil.

[4:16]  ³ sn The Hiphil imperfect (Kethib) means “cause to stumble.” This idiom (from hypocatastasis) means “bring injury/ruin to someone” (BDB 505-6 s.v. כָּשַׁל Hiph.1).

[20:11]  ⁴ sn In the first nine chapters of the book of Proverbs the Hebrew term נַעַר (na’ar) referred to an adolescent, a young person whose character was being formed in his early life.

[20:11]  ⁵ sn The Hebrew verb נָכַר (nakhar) means “to recognize” more than simply “to know.” Certain character traits can be recognized in a child by what he does (cf. NCV “by their behavior”).

[20:11]  ⁶ sn Character is demonstrated by actions at any age. But the emphasis of the book of Proverbs would also be that if the young child begins to show such actions, then the parents must try to foster and cultivate them; if not, they must try to develop them through teaching and discipline.
