OET interlinear ECC 5:3

uW Translation Notes:

Note 1 topic: figures-of-speech / parallelism

כִּ֛י בָּ֥א הַ⁠חֲל֖וֹם בְּ⁠רֹ֣ב עִנְיָ֑ן וְ⁠ק֥וֹל כְּסִ֖יל בְּ⁠רֹ֥ב דְּבָרִֽים

that/for/because/then/when he/it_came the=dream with,abundance_of cares and_[the],voice_of fool with,a_multitude_of words/messages

These two clauses mean basically the same thing. The second emphasizes the meaning of the first by repeating the same idea with different words. If it would be helpful to your readers, you could combine them and express the emphasis in another way. Alternate translation: [For a fool is known by his much activity and his many words]

Note 2 topic: figures-of-speech / ellipsis

וְ⁠ק֥וֹל כְּסִ֖יל בְּ⁠רֹ֥ב דְּבָרִֽים

and_[the],voice_of fool with,a_multitude_of words/messages

Solomon is leaving out some of the words that in many languages a sentence would need in order to be complete. You can supply these words from the context if that would be clearer in your language. Alternate translation: [and a fool’s voice comes with many words]

Note 3 topic: figures-of-speech / metonymy

וְ⁠ק֥וֹל כְּסִ֖יל

and_[the],voice_of fool

Here, the voice of a fool represents “what a fool says.” If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [and the words of a fool come]
