A priest must not leave the Temple during service

"You shall not even go out from the doorway of the tent of meeting, or you will die; for the LORD'S anointing oil is upon you." So they did according to the word of Moses.

Hebrew

ז וּמִפֶּתַח אֹהֶל מוֹעֵד לֹא תֵצְאוּ, פֶּן-תָּמֻתוּ--כִּי-שֶׁמֶן מִשְׁחַת יְהוָה, עֲלֵיכֶם; וַיַּעֲשׂוּ, כִּדְבַר מֹשֶׁה. {פ}

Greek

7 καὶ ἀπὸ τῆς θύρας τῆς σκηνῆς τοῦ μαρτυρίου οὐκ ἐξελεύσεσθε, ἵνα μὴ ἀποθάνητε· τὸ γὰρ ἔλαιον τῆς χρίσεως τὸ παρὰ κυρίου ἐφ᾿ ὑμῖν. καὶ ἐποίησαν κατὰ τὸ ῥῆμα Μωυσῆ.
