— 1 Chronicles 23:31, NASB
“And to offer all burnt sacrifices unto the Lord in the sabbaths, in the new moons, and on the set feasts, by number, according to the order commanded unto them, continually before the Lord:”
“and to offer all burnt-offerings unto Jehovah, on the sabbaths, on the new moons, and on the set feasts, in number according to the ordinance concerning them, continually before Jehovah; ”
“and to offer all burnt offerings to Yahweh, on the Sabbaths, on the new moons, and on the set feasts, in number according to the ordinance concerning them, continually before Yahweh;”
“and whenever burnt sacrifices were offered to the LORD on the Sabbath and at new moon festivals and assemblies. A designated number were to serve before the LORD regularly in accordance with regulations.”
“As well in the oblation of the holocausts of the Lord, as in the sabbaths and in the new moons, and the rest of the solemnities, according to the number and ceremonies prescribed for every thing, continually before the Lord.”
“At every offering of burned offerings to the Lord, on Sabbaths, and at the new moons, and on the regular feasts, in the number ordered by the law, at all times before the Lord;”
“And to offer all burnt sacrifices unto the Lord in the sabbaths, in the new moons, and on the set feasts, by number, according to the order commanded unto them, continually before the Lord:”
For their office is to assist the sons of Aaron with the service of the house of the LORD, in the courts and in the chambers and in the purifying of all holy things, even the work of the service of the house of God,

They are to stand every morning to thank and to praise the LORD, and likewise at evening,
and to offer all burnt offerings to the LORD, on the sabbaths, the new moons and the fixed festivals in the number set by the ordinance concerning them, continually before the LORD.
Thus they are to keep charge of the tent of meeting, and charge of the holy place, and charge of the sons of Aaron their relatives, for the service of the house of the LORD.
