OET interlinear LAM 4:2

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

בְּנֵ֤י צִיּוֹן֙ הַ⁠יְקָרִ֔ים הַ⁠מְסֻלָּאִ֖ים בַּ⁠פָּ֑ז

(Some words not found in UHB: sons_of Tsiyyōn/(Zion) (the),precious [who,were]_weighed with_(the),gold how regarded to,jars_of earthen work_of hands_of potter's )

Here the writer is speaking as if the people of Jerusalem were precious metal that could be weighed against fine gold. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [The precious sons of Zion, as valuable as fine gold]

Note 2 topic: figures-of-speech / activepassive

הַ⁠מְסֻלָּאִ֖ים בַּ⁠פָּ֑ז

(Some words not found in UHB: sons_of Tsiyyōn/(Zion) (the),precious [who,were]_weighed with_(the),gold how regarded to,jars_of earthen work_of hands_of potter's )

The expression weighed against fine gold is a passive verbal form. If it would be unnatural to use that form, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [whose value equaled fine gold]

Note 3 topic: figures-of-speech / simile

אֵיכָ֤ה נֶחְשְׁבוּ֙ לְ⁠נִבְלֵי־חֶ֔רֶשׂ

how (Some words not found in UHB: sons_of Tsiyyōn/(Zion) (the),precious [who,were]_weighed with_(the),gold how regarded to,jars_of earthen work_of hands_of potter's )

The point of this comparison is that just as jars of clay are cheap and easily broken, so the sons of Zion are now treated as worthless. If it would be helpful in your language, you could make this point explicitly. Alternate translation: [how people regard them as worthless, like jars of clay]
