καὶ συνήχθησαν εἰς Ιερουσαλημ λαὸς πολὺς τοῦ ποιῆσαι τὴν ἑορτὴν τῶν ἀζύμων ἐν τῷ μηνὶ τῷ δευτέρῳ ἐκκλησία πολλὴ σφόδρα
In the second month, a very great assembly gathered in Jerusalem to celebrate the Feast of Unleavened Bread (note: That is, the seven-day period after the Passover during which no leaven may be eaten; see Exodus 12:14–20.).
