¹⁴ And he appointed, according to the mishpat Dovid Aviv, the machlekot (divisions) of the Kohanim to their avodah service, and the Levi’im to their mishmerot (watches), to praise and minister before the Kohanim, as the requirement of every yom required; the Sho’arim (Gatekeepers) also by their machlekot (divisions) at every sha’ar; for thus was the mitzvot Dovid Ish HaElohim.
