We have here an account of the great solemnity of dedicating the altars, both that of burnt-offerings and that of incense; they had been sanctified before, when they were anointed (Lev 8:10, Lev 8:11), but now they were handselled, as it were, by the princes, with their free-will offerings.

On the seventh day--Surprise has been expressed by some that this work of presentation was continued on the Sabbath. But assuming that the seventh day referred to was a Sabbath (which is uncertain), the work was of a directly religious character, and perfectly in accordance with the design of the sacred day.
