They performed the service of their God and the service of purification, along with the singers and gatekeepers, as David and his son Solomon had prescribed.
The priests, Levites, singers, and gatekeepers perform their service and purification as David and Solomon prescribed.
This verse ties present worship to inherited royal patterns.
44And on that same day men were appointed over the rooms that housed the supplies, contributions, firstfruits, and tithes. The portions specified by the Law for the priests and Levites were gathered into these storerooms from the fields of the villages, because Judah rejoiced over the priests and Levites who were serving. 45They performed the service of their God and the service of purification, along with the singers and gatekeepers, as David and his son Solomon had prescribed. 46For long ago, in the days of David and Asaph, there were directors for the singers and for the songs of praise and thanksgiving to God. 47So in the days of Zerubbabel and Nehemiah, all Israel contributed the daily portions for the singers and gatekeepers. They also set aside daily portions for the Levites, and the Levites set aside daily portions for the descendants of Aaron.
