Young's Literal Translation

³⁰ and to stand, morning by morning, to give thanks, and to give praise to Jehovah, and so at evening;

³¹ and for all the burnt-offerings -- burnt-offerings to Jehovah for sabbaths, for new moons, and for appointed seasons, by number, according to the ordinance upon them continually, before Jehovah.

³² And they have kept the charge of the tent of meeting, and the charge of the sanctuary, and the charge of the sons of Aaron, their brethren, for the service of the house of Jehovah.
