OET interlinear NAH 2:6

uW Translation Notes:

Note 1 topic: translate-tense

שַׁעֲרֵ֥י הַ⁠נְּהָר֖וֹת נִפְתָּ֑חוּ וְ⁠הַֽ⁠הֵיכָ֖ל נָמֽוֹג

(Some words not found in UHB: gates_of of,the_rivers opened and,the,palace trembles )

The author uses the past tense here in order to refer to something that will certainly happen in the future. If it would not be natural to do that in your language, you could use the future tense. Alternate translation: [The gates of the rivers will open, and the palace will melt away]

Note 2 topic: translate-unknown

שַׁעֲרֵ֥י הַ⁠נְּהָר֖וֹת

(Some words not found in UHB: gates_of of,the_rivers opened and,the,palace trembles )

This refers to the gates that controlled the flow and direction of the river.

Note 3 topic: figures-of-speech / activepassive

נִפְתָּ֑חוּ

(Some words not found in UHB: gates_of of,the_rivers opened and,the,palace trembles )

If your language does not use a passive form like have been opened, you could express the idea in active form or in another way that is natural in your language. Alternate translation: [have opened] or [stand open]

Note 4 topic: figures-of-speech / metaphor

וְ⁠הַֽ⁠הֵיכָ֖ל נָמֽוֹג

and,the,palace trembles

The author is speaking of the palace as if it could melt to express how the flood of water will destroy the palace. If it would be helpful in your language, you could state the meaning plainly. Alternate translation: [and the floodwaters have destroyed the palace]
