Commentary for Ezekiel 41:2

וְרֹ֣חַב הַפֶּתַח֮ עֶ֣שֶׂר אַמּוֹת֒ וְכִתְפ֣וֹת הַפֶּ֔תַח חָמֵ֤שׁ אַמּוֹת֙ מִפּ֔וֹ וְחָמֵ֥שׁ אַמּ֖וֹת מִפּ֑וֹ וַיָּ֤מָד אָרְכּוֹ֙ אַרְבָּעִ֣ים אַמָּ֔ה וְרֹ֖חַב עֶשְׂרִ֥ים אַמָּֽה׃

And the breadth of the entrance was ten cubits; and the sides of the entrance were five cubits on the one side, and five cubits on the other side; and he measured the length thereof, forty cubits, and the breadth, twenty cubits.
