Uncovering A Leper

Καὶ ὁ λεπρὸς, ἐν ᾧ ἐστιν ἀφὴ, τὰ ἱμάτια αὐτοῦ ἔσται παραλελυμένα, καὶ ἡ κεφαλὴ αὐτοῦ ἀκάλυπτος. Διατί τοῦ λεπροῦ ἀκάλυπτον εἶναι κελεύει τὴν κεφαλὴν, καὶ τὰ ἱμάτια παραλελυμένα; Ἵνα γνωριστὸς ᾖ, καὶ μὴ μεταλαγχάνωσι τῆς ἀκαθαρσίας οἱ προσπελάζοντες. Οὕτως ὁ Ἀπόστολος περὶ τῶν ἁμαρτανόντων ἔφη· Στέλλεσθε ὑμᾶς ἀπὸ παντὸς ἀδελφοῦ ἀτάκτως περιπατοῦντος, καὶ μὴ κατὰ τὴν παράδοσιν, ἣν παρελάβετε παρ' ἡμῶν· καὶ Ἐάν τις ἀδελφὸς ὀνομαζόμενος, ἢ πόρνος, ἢ πλεονέκτης, ἢ εἰδωλολάτρης, ἢ μέθυσος, ἢ λοίδορος, ἢ ἅρπαξ· τῷ τοιούτῳ μὴ συνεσθίειν Ὠριγένης, Εκλογαι Εἰς  ἐν τον Λευϊτικον Source: Migne PG 17.20a-b

And the leper, he who is touched by the disease, his vestments you shall remove and his head uncover. 1 Why is it commanded that the head of the leper be uncovered and his vestments be removed? That it be known whether they who draw near to him will participate in uncleanliness. So the Apostle says, 'Withdraw yourselves from every brother who walks in disorder and not according to the tradition which you have received from us.' 2 And again, 'If someone who is named a brother is a fornicator or avaricious or an idolator or a drunkard, or a reviler, or a thief, do not eat with him.' 3  Origen, Fragment on Leviticus 1 Lev 13.45 2 2 Thess 3.6 3 1 Cor 5.11
