Divrey Hayamim Bais 30:15-17

Orthodox Jewish Bible

¹⁵ Then they slaughtered the Pesach on the fourteenth day of the second month; and the Kohanim and the Levi’im were ashamed, and they set themselves apart as kodesh, and brought olot to the Beis Hashem.

¹⁶ And they stood in their place after their prescribed manner, according to the Torat Moshe Ish HaElohim; the Kohanim sprinkled the dahm, which they received of the yad of the Levi’im.

¹⁷ For there were rabbim in HaKahal that were not set apart as kodesh; therefore the Levi’im had the charge of the shechitah (ritual slaughter) of the Pesachim for every one that was not tahor and therefore could not set them apart as kodesh unto Hashem.
