OET interlinear 2 SAM 8:14

uW Translation Notes:

Note 1 topic: figures-of-speech / parallelism

וַ⁠יָּ֨שֶׂם בֶּ⁠אֱד֜וֹם נְצִבִ֗ים בְּ⁠כָל־אֱדוֹם֙ שָׂ֣ם נְצִבִ֔ים

(Some words not found in UHB: and=he/it_assigned in,Edom garrisons in=all ʼEdōm put garrisons and=he/it_was all ʼEdōmites servants of,David and,he_gave_victory YHWH DOM Dāvid in,every which/who went )

These two phrases mean basically the same thing. The second emphasizes the meaning of the first by repeating the same idea with different words. If it would be helpful to your readers, you could combine them and express the emphasis in another way. Alternate translation: [And he stationed military garrisons throughout all of Edom]

Note 2 topic: figures-of-speech / ellipsis

בְּ⁠כָל־אֱדוֹם֙ שָׂ֣ם נְצִבִ֔ים

(Some words not found in UHB: and=he/it_assigned in,Edom garrisons in=all ʼEdōm put garrisons and=he/it_was all ʼEdōmites servants of,David and,he_gave_victory YHWH DOM Dāvid in,every which/who went )

The author is leaving out some of the words that in many languages a sentence would need in order to be complete. You can supply these words from the context if that would be clearer in your language. Alternate translation: [there were garrisons throughout all of Edom] or [he placed garrisons throughout all of Edom]

Note 3 topic: writing-endofstory

וַ⁠יּ֤וֹשַׁע יְהוָה֙ אֶת־דָּוִ֔ד בְּ⁠כֹ֖ל אֲשֶׁ֥ר הָלָֽךְ

(Some words not found in UHB: and=he/it_assigned in,Edom garrisons in=all ʼEdōm put garrisons and=he/it_was all ʼEdōmites servants of,David and,he_gave_victory YHWH DOM Dāvid in,every which/who went )

After providing some further details about the plunder David captured, the gifts he received, and how he defeated Edom, the author is once again making a summary comment about everything he has described since introducing a new event in 8:1. See how you translated the similar expression in 8:6.
