OET interlinear 1 KI 7:41

uW Translation Notes:

Note 1 topic: figures-of-speech / possession

וְ⁠גֻלֹּ֧ת הַ⁠כֹּתָרֹ֛ת

(Some words not found in UHB: pillars two and,the_bowls_of of,the_capitals which/who on/upon/above/on_account_of//he/it_went_in head of,the_pillars two and,the,networks two to,cover DOM two(fd) bowls_of of,the_capitals which/who on/upon/above/on_account_of//he/it_went_in head of,the_pillars )

The author is using the possessive form to describe capitals that were in the shape of bowls. (This refers to the bottom part of the capitals, as 7:20 indicates.) If a speaker of your language would not use the possessive form for this, you could express this idea in another way. Alternate translation: [and the bowl-shaped capitals]

Note 2 topic: figures-of-speech / idiom

רֹ֥אשׁ הָֽ⁠עַמֻּדִ֖ים שְׁתָּ֑יִם

head head (Some words not found in UHB: pillars two and,the_bowls_of of,the_capitals which/who on/upon/above/on_account_of//he/it_went_in head of,the_pillars two and,the,networks two to,cover DOM two(fd) bowls_of of,the_capitals which/who on/upon/above/on_account_of//he/it_went_in head of,the_pillars )

See how you translated the similar expression in 7:16. Alternate translation: [the tops of the two pillars]
