Do not leave the Temple unguarded

"So you shall attend to the obligations of the sanctuary and the obligations of the altar, so that there will no longer be wrath on the sons of Israel.

Hebrew

ה וּשְׁמַרְתֶּם, אֵת מִשְׁמֶרֶת הַקֹּדֶשׁ, וְאֵת, מִשְׁמֶרֶת הַמִּזְבֵּחַ; וְלֹא-יִהְיֶה עוֹד קֶצֶף, עַל-בְּנֵי יִשְׂרָאֵל.
