1 Chronicles 23:28-31

MLV(i) 28 For their office was to wait on the sons of Aaron for the service of the house of Jehovah, 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, also 29 for the showbread and for the fine flour for a meal offering, whether of unleavened wafers, or of what is baked in the pan, or of what is soaked and for all manner of measure and size. 30 And to stand every morning to thank and praise Jehovah and likewise at evening. 31 And to offer all burnt offerings to Jehovah, on the Sabbaths, on the new moons and on the set feasts, in number according to the ordinance concerning them, continually before Jehovah.
