Ezekiel — Command to Study the Temple
Ezekiel 43:10-11
God commands Ezekiel to describe the Temple to the House of Israel so that they may be ashamed of their sins, and to write it down so they may observe its entire form — implying that studying its structure is itself a commanded act with spiritual and moral significance.
אַתָּ֣ה בֶן־אָדָ֗ם הַגֵּ֤ד אֶת־בֵּֽית־יִשְׂרָאֵל֙ אֶת־הַבַּ֔יִת וְיִכָּלְמ֖וּ מֵעֲוֺנֽוֹתֵיהֶ֑ם וּמָדְד֖וּ אֶת־תׇּכְנִֽית׃ וְאִֽם־נִכְלְמ֞וּ מִכֹּ֣ל אֲשֶׁר־עָשׂ֗וּ צוּרַ֣ת הַבַּ֡יִת וּתְכוּנָת֡וֹ וּמוֹצָאָ֡יו וּמוֹבָאָ֣יו וְֽכׇל־צוּרֹתָ֡ו וְאֵ֣ת כׇּל־חֻקֹּתָיו֩ וְכׇל־צ֨וּרֹתָ֤ו וְכׇל־תּֽוֹרֹתָו֙ הוֹדַ֣ע אוֹתָ֔ם וּכְתֹ֖ב לְעֵינֵיהֶ֑ם וְיִשְׁמְר֞וּ אֶת־כׇּל־צוּרָת֛וֹ וְאֶת־כׇּל־חֻקֹּתָ֖יו וְעָשׂ֥וּ אוֹתָֽם׃
[Now] you, O mortal, describe the temple to the House of Israel, and let them measure its design. But let them be ashamed of their iniquities: When they are ashamed of all they have done, make known to them the plan of the temple and its layout, its exits and entrances—its entire plan, and all the laws and instructions pertaining to its entire plan. Write it down before their eyes, that they may faithfully follow its entire plan and all its laws.
Why it matters — This is the primary biblical source commanding Israel to study the Temple's design even in exile, establishing the learning itself as a mitzvah.
