Parallel
1 Chronicles 9:27
Swete's Septuagint · Berean Standard Bible
ὅτι ἐπʼ αὐτοὺς φυλακή· καὶ οὗτοι ἐπὶ τῶν κλειδῶν τὸ πρωὶ πρωὶ ἀνοίγειν τὰς θύρας τοῦ ἱεροῦ.
They would spend the night stationed around the house of God, because they were responsible for guarding it and opening it every morning.
