OET interlinear ECC 5:17

uW Translation Notes:

Note 1 topic: figures-of-speech / infostructure

כָּל יָמָ֖י⁠ו בַּ⁠חֹ֣שֶׁךְ יֹאכֵ֑ל

all/each/any/every his/its=days in,darkness eats

If it would be more natural in your language, you may want to put the action he eats before the expressions of time and manner all his days in darkness. Alternate translation: [he eats in darkness all his days]

Note 2 topic: figures-of-speech / hyperbole

כָּל יָמָ֖י⁠ו

all/each/any/every his/its=days

Solomon says all his days as an extreme statement for emphasis. If it would be helpful in your language, you could use a different way to express the emphasis. Alternate translation: [his entire life]

Note 3 topic: figures-of-speech / metaphor

בַּ⁠חֹ֣שֶׁךְ יֹאכֵ֑ל

in,darkness eats

Here Solomon is speaking as if the man’s misery were darkness. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [in misery he eats]

Note 4 topic: figures-of-speech / abstractnouns

וְ⁠חָלְי֥⁠וֹ

and,sickness_of,his

If your language does not use an abstract noun for the idea of sickness, you could express the same idea in another way. Alternate translation: [and his poor health]

Note 5 topic: figures-of-speech / abstractnouns

וְ⁠כָעַ֥ס הַרְבֵּ֖ה

and,he_is_vexed much

If your language does not use an abstract noun for the idea of vexation, you could express the same idea in another way. Alternate translation: [and greatly vexed]
