Amsal 19:10

19:10 Luxury is not appropriate ¹  for a fool; ² 

how much less for a servant to rule over princes! ³ 

Amsal 30:29

30:29 There are three things that are magnificent ⁴  in their step,

four things that move about magnificently: ⁵ 

[19:10]  ¹ tn The form נָאוֶה (na’veh) is an adjective meaning “seemly; comely” in the older English versions like KJV, ASV, “fitting” in more recent ones (e.g., NASB, NIV, NRSV). The verbal root נוֹה only occurs in the Pilel stem; but it also has the basic meaning of “being fitting; being comely.” In this sentence the form is a predicate adjective.

[19:10]  ² sn The verse is simply observing two things that are misfits. It is not concerned with a fool who changes and can handle wealth, or a servant who changes to become a nobleman. It is focused on things that are incongruous.

[19:10]  ³ sn In the ancient world the prince would be trained for his rule (hence, one of the original purposes of Proverbs). A slave ruling over princes would be arrogant and cruel, or foolish and unwise. For other unbearable things, e.g., 11:22; 17:7; 26:1; and 30:21-23.

[30:29]  ⁴ tn The form מֵיטִיבֵי (metibe) is the Hiphil participle, plural construct. It has the idea of “doing good [in] their step.” They move about well, i.e., magnificently. The genitive would be a genitive of specification.

[30:29]  ⁵ tn The construction uses the Hiphil participle again (as in the previous line) followed by the infinitive construct of הָלַךְ (halakh). This forms a verbal hendiadys, the infinitive becoming the main verb and the participle before it the adverb.
