Parallel
2 Chronicles 30:17
Rahlfs Septuagint (1935) · Berean Standard Bible
ὅτι πλῆθος τῆς ἐκκλησίας οὐχ ἡγνίσθη καὶ οἱ Λευῖται ἦσαν τοῦ θύειν τὸ φασεκ παντὶ τῷ μὴ δυναμένῳ ἁγνισθῆναι τῷ κυρίῳ
Since there were many in the assembly who had not consecrated themselves, the Levites were in charge of slaughtering the Passover lambs for every unclean person to consecrate the lambs to the LORD.
