Еврейская мысль к Диврей ха-ямим Б 3:15

וַיַּ֜עַשׂ לִפְנֵ֤י הַבַּ֙יִת֙ עַמּוּדִ֣ים שְׁנַ֔יִם אַמּ֕וֹת שְׁלֹשִׁ֥ים וְחָמֵ֖שׁ אֹ֑רֶךְ וְהַצֶּ֥פֶת אֲשֶׁר־עַל־רֹאשׁ֖וֹ אַמּ֥וֹת חָמֵֽשׁ׃ (ס)

Также он сделал перед домом два столба высотой тридцать пять локтей, и столица, которая была на вершине каждого из них, была пятью локтями.

The Third Beit HaMikdash

The fact that the measure of the pillars used in the Beis HaMikdash built by King Shlomoh is referred to as komah in the book of Melachim,7I Melachim 7:15. but as orech in Divrei HaYamim8II Divrei HaYamim 3:15. does not contradict the above. In Divrei HaYamim, the pillars were measured as they lay on the ground [before being erected in the building]. Therefore, they are described by the term orech, “length.” [In contrast, in Melachim,] the pillars are described as they stood, therefore, the term komah, “stature,” is used.
