Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ ἐποίησαν οἱ υἱοὶ Ισραηλ οἱ εὑρεθέντες ἐν Ιερουσαλημ τὴν ἑορτὴν τῶν ἀζύμων ἑπτὰ ἡμέρας ἐν εὐφροσύνῃ μεγάλῃ καὶ καθυμνοῦντες τῷ κυρίῳ ἡμέραν καθ᾿ ἡμέραν καὶ οἱ ἱερεῖς καὶ οἱ Λευῖται ἐν ὀργάνοις τῷ κυρίῳ
The Israelites who were present in Jerusalem celebrated the Feast of Unleavened Bread for seven days with great joy, and the Levites and priests praised the LORD day after day, accompanied by loud instruments of praise to the LORD (note: Or day after day, with all their strength to the LORD. Literally day after day, with loud instruments to the LORD.).
