1 Chronicles 24:5-7

Complete Jewish Bible

⁵ They were assigned [periods of service] by lot, the one group equally with the other, since both the descendants of El‘azar and the descendants of Itamar had officers of the sanctuary and officers of God. ⁶ Sh’ma‘yah the son of N’tan’el the secretary, one of the L’vi’im, recorded them in the presence of the king, the officers, Tzadok the cohen, Achimelekh the son of Evyatar, and the clan leaders of the cohanim and of the L’vi’im — with two clan divisions taken from El‘azar for each one from Itamar.
