OET interlinear EXO 26:21

uW Translation Notes:

Note 1 topic: figures-of-speech / explicit

שְׁנֵ֣י אֲדָנִ֗ים תַּ֚חַת הַ⁠קֶּ֣רֶשׁ הָֽ⁠אֶחָ֔ד וּ⁠שְׁנֵ֣י אֲדָנִ֔ים תַּ֖חַת הַ⁠קֶּ֥רֶשׁ הָ⁠אֶחָֽד

(Some words not found in UHB: and,forty bases_of,their silver two_of bases below/instead_of the,frame the=one and,two_of bases below/instead_of the,frame the=one )

The effect of this is to start a list, and the hearer will assume it should be completed. Try to translate this in the way that a speaker of your language would give instructions that are meant to be carried out on a whole group of objects. See how you translated this in Exodus 26:19. Alternate translation: [two bases under the first frame, and then two bases under the next frame, and so on for all the frames]
