OET interlinear 1 SAM 12:2

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

הַ⁠מֶּ֣לֶךְ ׀ מִתְהַלֵּ֣ךְ לִ⁠פְנֵי⁠כֶ֗ם & וַ⁠אֲנִי֙ הִתְהַלַּ֣כְתִּי לִ⁠פְנֵי⁠כֶ֔ם

(Some words not found in UHB: and=now see/lo/see! the=king walking_around/wandering before,,you(pl) and,I old and,I_am_gray_haired and,sons_of,my here,they [are]_with,you(pl) and,I walked before,,you(pl) since,youth(s)_of,my until the=day (the),this )

Samuel is speaking as if the Israelites were actually traveling on a path and the king was walking ahead of them, and as if he had walked ahead of them himself. He is using this image to represent leadership. If it would be clearer in your language, you could state the meaning plainly. Alternate translation: [the king is leading you … Now I have been leading you]

Note 2 topic: figures-of-speech / parallelism

וַ⁠אֲנִי֙ זָקַ֣נְתִּי וָ⁠שַׂ֔בְתִּי

and,I and,I (Some words not found in UHB: and=now see/lo/see! the=king walking_around/wandering before,,you(pl) and,I old and,I_am_gray_haired and,sons_of,my here,they [are]_with,you(pl) and,I walked before,,you(pl) since,youth(s)_of,my until the=day (the),this )

These two phrases mean basically the same thing. The first phrase makes a general statement, and the second phrase gives a specific example that confirms it. It may be clearer in your language to connect the phrases with a word other than and in order to show that the second phrase is repeating the idea in the first one, not saying something additional. Alternate translation: [Now I myself have aged, indeed, I have become gray-headed]

Note 3 topic: figures-of-speech / merism

מִ⁠נְּעֻרַ֖⁠י עַד־הַ⁠יּ֥וֹם הַ⁠זֶּֽה

(Some words not found in UHB: and=now see/lo/see! the=king walking_around/wandering before,,you(pl) and,I old and,I_am_gray_haired and,sons_of,my here,they [are]_with,you(pl) and,I walked before,,you(pl) since,youth(s)_of,my until the=day (the),this )

Samuel is referring to all of life by naming two extremes, my youth and this day. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [for my entire life]
