Rashi on Numbers 4:16/רש"י על במדבר ד׳:ט״ז

1ופקדת אלעזר AND THE CHARGE OF ELEAZAR … [WERE THE OIL FOR THE LIGHT, AND THE INCENSE OF AROMATICS, AND THE CONTINUAL MEAL OFFERING, AND THE ANOINTING OIL] — This means: the charge of Eleazar who was appointed over them to carry them were the oil, and the incense and the anointing oil. As regards the continual meal-offering mentioned here, upon him lay the charge to give orders and to urge on that it should be offered at the time when they encamped.

2פקדת כל המשכן means: and further he was appointed over the burden of the sons of Kohath, i.e., to give each man orders regarding his service and his burden, which was the Tabernacle and all that was therein — all the articles set forth above in this section. The burden of the sons of Gershon and of the sons of Merari, however, which did not appertain to things of most holy character, was carried out by order of Ithamar, as is set forth in the section commencing with the word נשא (vv. 21—34).
