27. See Exo_30:7. Moses, however, not Aaron, according to the present writer, begins the daily services (cf. vv. 23, 25, 29), and maintains them during the first eight days till the priests are installed (cf. Exo_29:35, Lev_8:33; Lev_9:1).

and put water there to wash withal; for the priests to wash their hands and feet with; a type of that laver or fountain opened for the house of David and inhabitants of Jerusalem to wash in, Zac 13:1.

This is wisely and seasonably added, because this was a work peculiar to the priest, and not to be done by Moses without God’s express command

ויקטר עליו קטרת AND HE CAUSED THE INCENSE OF AROMATICS TO ASCEND UPON IT in the morning and in the evening, as it is said, (Exodus 30:7, 8) “[And Aaron shall cause incense of aromatics to ascend thereon in fumes] every morning when he trimmeth the lamps, [and when he trimmeth the lamps at even etc.]”.

AND HE BURNT THEREON INCENSE OF SWEET SPICES. All the seven days of the installation Moses burnt the incense on the golden altar, and even though he was not specifically told to do so when he was commanded, … he did so nonetheless, for he understood that he was to do so from all the other acts of service, since G-d had commanded him here that he should set the bread and kindle the lamps. Similarly, and he offered upon it the burnt-offering and the meal-offering means that Moses was the one who offered them, for thus he was commanded, Now this is that which thou shalt offer upon the altar, meaning that he was to begin to do this when performing the Service during the days of the installation, for all commands there [about the burnt- and the meal-offering], Verses 39-41. refer to Moses’ service. Afterward, it says, It shall be a continual burnt-offering throughout your generations, Verse 42. meaning that the priests shall do throughout the generations as Moses now did. Therefore in the section of Pinchas it says about this Daily Offering, It is a continual burnt-offering, which was offered in Mount Sinai, meaning that Moses began doing it there. Thus Moses our Teacher was the first priest in all these acts of service, therefore he also burnt the incense. Perhaps this is included in the words, and thou shalt put the golden altar for incense, Verse 5. meaning that he should immediately burn the incense on it. And that which is said at the time of the command, And thou shalt put it before the veil… and Aaron shall burn thereon the incense of sweet spices, refers to the proper time, from the day that Aaron begins his service and forever afterwards, [and does not exclude Moses’ service during the seven days], for so He said, And when Aaron lighteth the lamps at dusk, Verse 8. and he only lit them from that day on, for here Moses was clearly commanded: and thou shalt light the lamps thereof. Now in Rashi’s commentary I have seen this text: “And he — Aaron — burnt thereon incense (of sweet spices) morning and evening, as it is said, every morning, when he dresseth the lamps, he shall burn it. And when Aaron lighteth the lamps at dusk etc.” But I do not know if this is the scribe’s mistake.
