OET interlinear NUM 3:26

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

וְ⁠קַלְעֵ֣י הֶֽ⁠חָצֵ֗ר

and,the_curtains_of of,the_courtyard

The implication is that these were the curtains that marked off and formed a fence around the courtyard, as described in Exodus 27:9–15. You could include this information if that would be helpful to your readers. Alternate translation: [and the curtains that marked off the courtyard]

Note 2 topic: figures-of-speech / idiom

אֲשֶׁ֧ר עַל־הַ⁠מִּשְׁכָּ֛ן וְ⁠עַל־הַ⁠מִּזְבֵּ֖חַ סָבִ֑יב

which/who on/upon/above/on_account_of//he/it_went_in the,tabernacle and,at the,altar around

The author is using on the Dwelling and on the altar all around as a common expression of his culture to mean “that contains the sacred tent and the altar.” If this phrase does not have that meaning in your language, you could use a comparable expression from your language that does have that meaning, or you could state the meaning plainly. Alternate translation: [that contains the Dwelling and the altar]

וְ⁠אֵת֙ מֵֽיתָרָ֔י⁠ו לְ⁠כֹ֖ל עֲבֹדָתֽ⁠וֹ

and=DOM tent-cords_of,its to=all/each/any/every service_of,its

Here, the pronoun its could refer to: (1) the curtains mentioned in this and the previous verse. Alternate translation: [and the ropes for the curtains for all their service] (2) the Dwelling. Alternate translation: [and the ropes for the Dwelling for all its service]

Note 4 topic: figures-of-speech / abstractnouns

לְ⁠כֹ֖ל עֲבֹדָתֽ⁠וֹ

to=all/each/any/every service_of,its

If your language does not use an abstract noun for the idea of service, you could express the same idea in another way. Alternate translation: [for all the ways that it needs to be served]
