OET interlinear ZEC 12:8

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

הַ⁠נִּכְשָׁ֥ל בָּ⁠הֶ֛ם

the_[one,who]_stumbles (is)_in=them

Here Zechariah is speaking of a weak or feeble person as if he were a stumbler. Your language may have a comparable expression that you can use in your translation, or you could state the meaning plainly. Alternate translation: [and the weakest one among them]

Note 2 topic: figures-of-speech / nominaladj

הַ⁠נִּכְשָׁ֥ל

(Some words not found in UHB: in_the=day (the)=that shield YHWH behind inhabitants_of Yerushalayim and=it_was the_[one,who]_stumbles (is)_in=them in_the=day (the)=that like,David and,the_house_of Dāvid like=ʼElohīm like,the_angel_of YHWH before,,them )

Zechariah is using the adjective stumbler as a noun to mean a certain kind of person. Your language may use adjectives in the same way. If not, you can translate this adjective with an equivalent phrase. Alternate translation: [the one who stumbles]

Note 3 topic: figures-of-speech / hyperbole

וְ⁠הָיָ֞ה & כְּ⁠דָוִ֑יד וּ⁠בֵ֤ית דָּוִיד֙ כֵּֽ⁠אלֹהִ֔ים

and=it_was & like,David and,the_house_of Dāvid like=ʼElohīm

Zechariah says will be like David, and the house of David like God as an extreme statement for emphasis. If it would be helpful in your language, you could use a different way to express the emphasis. Alternate translation: [will be strong like David was, and the house of David will seem as powerful as God]

Note 4 topic: figures-of-speech / simile

וּ⁠בֵ֤ית דָּוִיד֙ כֵּֽ⁠אלֹהִ֔ים כְּ⁠מַלְאַ֥ךְ יְהוָ֖ה

and,the_house_of Dāvid like=ʼElohīm like,the_angel_of YHWH

The point of this comparison is that just as God and the angel of Yahweh are powerful, so the house of David will be powerful as they lead the people. If it would be helpful in your language, you could make this point explicitly. Alternate translation: [and the house of David will be as powerful as God is, as powerful as the angel of Yahweh]

Note 5 topic: figures-of-speech / metonymy

כְּ⁠מַלְאַ֥ךְ יְהוָ֖ה לִ⁠פְנֵי⁠הֶֽם

like,the_angel_of YHWH before,,them

Here, their face represents their presence, so the phrase means going ahead of the people to lead them. If it would be helpful in your language, you could use an equivalent expression or plain language. Alternate translation: [like having the angel of Yahweh fighting in front of them]
