OET interlinear 1 KI 2:11

uW Translation Notes:

Note 1 topic: figures-of-speech / infostructure

וְ⁠הַ⁠יָּמִ֗ים אֲשֶׁ֨ר מָלַ֤ךְ דָּוִד֙ עַל־יִשְׂרָאֵ֔ל אַרְבָּעִ֖ים שָׁנָ֑ה בְּ⁠חֶבְר֤וֹן מָלַךְ֙ שֶׁ֣בַע שָׁנִ֔ים וּ⁠בִ⁠ירוּשָׁלִַ֣ם מָלַ֔ךְ שְׁלֹשִׁ֥ים וְ⁠שָׁלֹ֖שׁ שָׁנִֽים

(Some words not found in UHB: and,the,days which/who reigned Dāvid on/upon/above/on_account_of//he/it_went_in Yisrael forty year in,Hebron reigned seven years and,in,Jerusalem reigned thirty and,three years )

If it would be more natural in your language, you could state the smaller numbers first and then give the total. Alternate translation: [David reigned in Hebron 7 years, and he reigned in Jerusalem 33 years. So all the days that David reigned over Israel were 40 years]

Note 2 topic: figures-of-speech / metonymy

וְ⁠הַ⁠יָּמִ֗ים & אַרְבָּעִ֖ים שָׁנָ֑ה

(Some words not found in UHB: and,the,days which/who reigned Dāvid on/upon/above/on_account_of//he/it_went_in Yisrael forty year in,Hebron reigned seven years and,in,Jerusalem reigned thirty and,three years )

Here, days represent time, since time consists of days. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [And the time … was 40 years]
