Ezra 8:18-20

18Since the gracious hand of our God was on us, they brought us Sherebiah  — a man of insight from the descendants of Mahli, a descendant of Levi son of Israel — along with his sons and brothers, 18 men,

19plus Hashabiah, along with Jeshaiah, from the descendants of Merari, and his brothers and their sons, 20 men.

20There were also 220 of the temple servants, who had been appointed by David and the leaders for the work of the Levites. All were identified by name.
