2 Chronicles 29:15-17

Living Bible

¹⁵ They in turn summoned their fellow Levites and sanctified themselves, and began to clean up and sanctify the Temple, as the king (who was speaking for the Lord) had commanded them. ¹⁶ The priests cleaned up the inner room of the Temple and brought out into the court all the filth and decay they found there. The Levites then carted it out to Kidron Brook. ¹⁷ This all began on the first day of April, and by the eighth day they had reached the outer court, which took eight days to clean up, so the entire job was completed in sixteen days.
