Exode 19:20-22

20κατέβη δὲ κύριος ἐπὶ τὸ ὄρος τὸ Σινα ἐπὶ τὴν κορυφὴν τοῦ ὄρους· καὶ ἐκάλεσεν κύριος Μωυσῆν ἐπὶ τὴν κορυφὴν τοῦ ὄρους, καὶ ἀνέβη Μωυσῆς.

21καὶ εἶπεν ὁ θεὸς πρὸς Μωυσῆν λέγων Καταβὰς διαμάρτυραι τῷ λαῷ, μήποτε ἐγγίσωσιν πρὸς τὸν θεὸν κατανοῆσαι καὶ πέσωσιν ἐξ αὐτῶν πλῆθος·

22καὶ οἱ ἱερεῖς οἱ ἐγγίζοντες κυρίῳ τῷ θεῷ ἁγιασθήτωσαν, μήποτε ἀπαλλάξῃ ἀπ αὐτῶν κύριος.
