Ethan: Son of Zerak: Two Levites

…the son of Ethan, the son of Zimmah, the son of Shimei,

On the left were their kinsmen, the sons of Merari: Ethan the son of Kishi, the son of Abdi, the son of Malluch,

So the Levites appointed Heman son of Joel; from his brothers, Asaph son of Berechiah; from their brothers the Merarites, Ethan son of Kushaiah;

The musicians Heman, Asaph, and Ethan were to sound the bronze cymbals.
