Parallel
1 Chronicles 9:33
Rahlfs Septuagint (1935) · Berean Standard Bible
καὶ οὗτοι ψαλτῳδοὶ ἄρχοντες τῶν πατριῶν τῶν Λευιτῶν διατεταγμέναι ἐφημερίαι ὅτι ἡμέρα καὶ νὺξ ἐπ᾿ αὐτοῖς ἐν τοῖς ἔργοις
Those who were musicians, the heads of Levite families, stayed in the temple chambers and were exempt from other duties because they were on duty day and night.
