2 Chronicles 29:15-17

Revised Standard Version Catholic Edition

¹⁵ They gathered their brethren, and sanctified themselves, and went in as the king had commanded, by the words of the Lord, to cleanse the house of the Lord. ¹⁶ The priests went into the inner part of the house of the Lord to cleanse it, and they brought out all the uncleanness that they found in the temple of the Lord into the court of the house of the Lord; and the Levites took it and carried it out to the brook Kidron. ¹⁷ They began to sanctify on the first day of the first month, and on the eighth day of the month they came to the vestibule of the Lord; then for eight days they sanctified the house of the Lord, and on the sixteenth day of the first month they finished.
