1 Chronicles 23:30-32

Wycliffe Bible

³⁰ And the deacons shall be, that they stand early, for to acknowledge and sing to the Lord, and in like manner at eventide, (And every morning, the Levites shall be on duty to give thanks and to sing to the Lord, and in like manner every evening,)

³¹ as well in the offering of burnt sacrifices of the Lord, as in sabbaths, and calends, and other solemnities, by the number and ceremonies of each thing, continually before the Lord; (as well as at the offering of burnt sacrifices to the Lord, on sabbaths, and calends, and the other Feast Days, by their prescribed number, continually before the Lord;)

³² and that they keep the observances of the tabernacle of the bond of peace of the Lord, and the custom of the saintuary, and the observance of the sons of Aaron, their brethren, that they minister in the house of the Lord. (and that they keep the observances of the Tabernacle of the Covenant of the Lord, that is, the Tabernacle of the Witnessing, and the customs of the sanctuary, and the observances of the sons of Aaron, their kinsmen, and so serve in the House of the Lord.)
