the,pillars (Some words not found in UHB: and,[it_was]_paneled with,cedar from,above on/upon/above/on_account_of//he/it_went_in the,side-chambers which/who on/upon/above/on_account_of//he/it_went_in the,pillars forty and,five five ten the,row )

The author is using the phrase 15 the row as a common expression of his culture to mean that there were 15 pillars in each row that he is describing. 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: [45 pillars that were in rows of 15]
