On Pascha · §1.54

Keep it until the fourteenth

And as there the sheep is not sacrificed at the same time as it is taken on the tenth, but on the fourteenth, five days having passed, so here too the one who has taken the true sheep, that is Christ, does not at once sacrifice and chew, but five days having passed after the taking of him.

Greek

Καὶ ὡς ἐκεῖ οὐχ ἅμα τῷ λαβεῖν τῇ δεκάτῃ τὸ πρόβατον θύεται ἀλλὰ τῇ τεσσαρεσκαιδεκάτῃ, πέντε ἡμερῶν διαγενομένων, καὶ ἐνθάδε|| [ὁ τὸ ἀληθινὸν πρόβατον λαβών, τοῦτ' ἔστιν X(ριστό)ν, οὐκ εὐθέως θύει καὶ τρώγει, ἀλλ' ἡμερῶν πέντε διαγενομένων μετὰ τὴν λῆψιν αὐτοῦ.
