Now these are the singers, the heads of ancestral houses of the Levites, living in the chambers of the temple free from other service, for they were on duty day and night.
Take position in the holy place according to the groupings of the ancestral houses of your kindred the people, and let there be Levites for each division of an ancestral house.
You shall remain at the entrance of the tent of meeting day and night for seven days, keeping the Lord’s charge so that you do not die, for so have I been commanded.”
At that time the Lord set apart the tribe of Levi to carry the ark of the covenant of the Lord, to stand before the Lord to minister to him and to bless in his name, to this day.
For this reason they are before the throne of God and worship him day and night within his temple, and the one who is seated on the throne will shelter them.
