[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.
[30:22] 4 sn A servant coming to power could become a tyrant if he is unaccustomed to the use of such power, or he might retain the attitude of a servant and be useless as a leader.
[30:22] 5 tn Heb “filled with food” (so ASV); NASB “satisfied with food”; NAB, NRSV “glutted with food”; CEV “who eats too much”; NLT “who prospers.”
[30:22] sn The expression stuffed with food probably represents prosperity in general. So the line portrays someone who suddenly comes into wealth, but continues to be boorish and irreligious.
