וּ⁠בִ⁠בְנוֹתֶ֜י⁠הָ & וּ⁠בִ⁠בְנוֹתֶ֗י⁠הָ

and,in,daughters_of,its & and,in,daughters_of,its

See how you translated the same expression in 1:27. Alternate translation: [and in the surrounding villages … and in the surrounding villages]

Note 2 topic: figures-of-speech / rquestion

וּ⁠מַדּ֥וּעַ לֹֽא־הִצַּלְתֶּ֖ם בָּ⁠עֵ֥ת הַ⁠הִֽיא

and,why? not (Some words not found in UHB: when,dwelt Yisrael in,Heshbon and,in,daughters_of,its and,in,Aroer and,in,daughters_of,its and=on/over=all the,cities which/who on/upon/above/on_account_of//he/it_went_in banks_of ʼArnōn three hundreds year and,why? not recover at,time (the),that )

The messengers are using the question form for emphasis. If a speaker of your language would not use the question form for that purpose, you could translate this as a statement or as an exclamation. Alternate translation: [but you did not deliver during that time!]

Note 3 topic: figures-of-speech / yousingular

לֹֽא־הִצַּלְתֶּ֖ם

not (Some words not found in UHB: when,dwelt Yisrael in,Heshbon and,in,daughters_of,its and,in,Aroer and,in,daughters_of,its and=on/over=all the,cities which/who on/upon/above/on_account_of//he/it_went_in banks_of ʼArnōn three hundreds year and,why? not recover at,time (the),that )

The word you is plural here because the messengers are asking why none of the Ammonites tried to recapture the land during the time they are describing. If your language marks that distinction, you could use the plural form in your translation. Other languages may have other ways of indicating this. Alternate translation: [did you Ammonites not deliver]
