OET interlinear 1 KI 3:14

uW Translation Notes:

Note 1 topic: grammar-connect-words-phrases

וְ⁠אִ֣ם ׀ תֵּלֵ֣ךְ בִּ⁠דְרָכַ֗⁠י לִ⁠שְׁמֹ֤ר חֻקַּ⁠י֙ וּ⁠מִצְוֺתַ֔⁠י

and=if (Some words not found in UHB: and=if walk in,ways_of,my to=guard/protect statutes_of,my and,commandments_of,my just=as walked Dāvid I_will_show=you(ms) and,I_will_make_long DOM days_of,your )

If the connection between the first and second phrases is not clear, you may want to use a connecting word other than to in order to show how the second phrase relates to the first one. Alternate translation: [And if you walk in my ways by keeping my statutes and my commandments]

Note 2 topic: figures-of-speech / doublet

חֻקַּ⁠י֙ וּ⁠מִצְוֺתַ֔⁠י

(Some words not found in UHB: and=if walk in,ways_of,my to=guard/protect statutes_of,my and,commandments_of,my just=as walked Dāvid I_will_show=you(ms) and,I_will_make_long DOM days_of,your )

The terms statutes and commandments mean similar things. God is using the two terms together for emphasis. If it would be clearer for your readers, you could express the emphasis with a single phrase. Alternate translation: [all of my laws]

Note 3 topic: figures-of-speech / metonymy

אֶת־יָמֶֽי⁠ךָ

DOM days_of,your

Here, days represents a period of time, specifically Solomon’s lifetime. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [your life]
