na.va describes something issuing forth, especially an outpouring of speech, praise, or sayings, and also bubbling liquid or water imagery.

The attested usage most often depicts words, praise, wisdom, or folly coming forth in an abundant verbal outflow; it also occurs in imagery of bubbling water and in the physical effect of oil bubbling. In Psalm 19:3 and Psalm 59:8, the APB’s loose wording does not clearly isolate the term’s contribution.

1. Pouring forth words, praise, or sayings · dominant

   This is the main verbal use: in Proverbs 15:2 the APB renders the foolish lip as one that “pours out folly,” while Proverbs 15:28 contrasts the righteous heart’s answer with the wicked lip that “bubbles bad.” In Proverbs 1:23, Psalm 119:171, Psalm 145:7, Psalm 78:2, and Psalm 94:4, the surrounding clauses concern spirit, praise, goodness, riddles, or arrogant speech coming forth.

2. Bubbling water imagery · occasional

   In Proverbs 18:4, the Qal active participle occurs in the saying that compares a man’s words with “deep waters” and “a bubbling torrent”; the APB presents the image alongside “a fountain of wisdom.”

   Proverbs 18:4
3. Oil made to bubble · rare

   In Ecclesiastes 10:1, the Hiphil imperfect appears in the clause about dead flies affecting perfumer’s oil; the APB renders the result as making the oil “stink and bubble.”

   Ecclesiastes 10:1

In the Anselm Project Bible: Across the supplied verses, the APB variously uses “bubble,” “pours out,” “pour forth,” and “utter” in clauses where the term occurs. In Psalm 19:3 and Psalm 59:8, its whole-verse wording does not make a specific English correspondence clear.
