1 Chronicles 16:37
Ver. 37. So he left there, before the ark of the covenant of the Lord, Asaph and his brethren,.... Whom he, that is, David, had appointed for the service of it:
to minister before the ark continually; in singing the praises of God:
as every day's work required; at the time of the morning and evening sacrifice, as Jarchi and Kimchi interpret it.
