Amsal 1:18

1:18 but these men lie in wait for their own blood, ¹ 

they ambush their own lives! ² 

Amsal 4:16

4:16 For they cannot sleep unless they cause harm; ³ 

they are robbed of sleep ⁴  until they make someone stumble. ⁵ 

[1:18]  ¹ sn They think that they are going to shed innocent blood, but in their blindness they do not realize that it is their own blood they shed. Their greed will lead to their destruction. This is an example of ironic poetic justice. They do not intend to destroy themselves; but this is what they accomplish.

[1:18]  ² tn Heb “their own souls.” The term נֶפֶשׁ (nefesh, “soul”) is used as a metonymy (= soul) of association (= life). The noun נֶפֶשׁ often refers to physical “life” (Exod 21:23; Num 17:3; Judg 5:18; Prov 12:10; BDB 659 s.v. 3.c).

[4:16]  ³ 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]  ⁴ sn Heb “their sleep is robbed/seized”; these expressions are metonymical for their restlessness in plotting evil.

[4:16]  ⁵ 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).
