OET interlinear LAM 4:6

uW Translation Notes:

Note 1 topic: figures-of-speech / metonymy

וַ⁠יִּגְדַּל֙ עֲוֺ֣ן בַּת־עַמִּ֔⁠י מֵֽ⁠חַטַּ֖את סְדֹ֑ם

(Some words not found in UHB: and,it_has_become_great punishment_of daughter_of my_people_of,my more,than_the_sin_of Sodom [which,was]_overthrown in moment and=not laid on,it hand )

Here, iniquity could represent: (1) the sin itself, meaning the sinfulness of the people is worse than the sinfulness of Sodom. Alternate translation: [the wickedness of the daughter of my people is greater than the wickedness of Sodom] or (2) the punishment for sin, meaning God has punished the people more severely than he punished Sodom. The UST follows this reading. Alternate translation: [the punishment of the daughter of my people is greater than the punishment of Sodom]

Note 2 topic: figures-of-speech / abstractnouns

וַ⁠יִּגְדַּל֙ עֲוֺ֣ן בַּת־עַמִּ֔⁠י מֵֽ⁠חַטַּ֖את סְדֹ֑ם

(Some words not found in UHB: and,it_has_become_great punishment_of daughter_of my_people_of,my more,than_the_sin_of Sodom [which,was]_overthrown in moment and=not laid on,it hand )

If your language does not use abstract nouns for the ideas of iniquity and sin, you could express the same idea in another way. Alternate translation: [And the way the daughter of my people has acted wickedly is worse than the way Sodom sinned]

Note 3 topic: figures-of-speech / idiom

וְ⁠לֹא־חָ֥לוּ בָ֖⁠הּ יָדָֽיִם

and=not laid on,it hand

This could mean: (1) no one expressed grief for Sodom, that is, no one wrung their hands in anguish over its destruction. Alternate translation: [and no one grieved for her] or (2) no human hands were involved in its destruction because God destroyed it suddenly. Alternate translation: [and no hands helped her]
