Matthew Poole and continuators on Numbers 7:1

1 AND it came to pass on the day that Moses had fully set up the tabernacle, and had anointed it b, and sanctified it, and all the instruments thereof, both the altar, and all the vessels thereof, and had anointed them, and sanctified them;

Either 1. precisely, and so this history, as many others is put out of its proper place, and this chapter and the 8th. and 9th. and 10th. and 11th. should follow next after Exod. 40. and this day is the same on which the Tabernacle was erected, which was the first day of the first moneth of the 2 year, Exod. 40. 17, 18. Or 2. largely, day being put for time, and on the day, for about the time, or, a little after the time. And thus it seems to be taken here, because all the princes did not offer these things upon one and the same day, but on several dayes, as here it follows. And so there is no disorder in the history, and this chapter comes in its proper place, and those things were done in the second moneth of the second year after the Tabernacle and Altar and all other instruments thereof were anointed, as is here expressed; and after the Levites were separated to the service of the Tabernacle and appointed to their several works, as is manifest from ver. 5, 6, 7, 8, 9. which was done about a moneth after the Tabernacle was erected, &c. and after the numbring of the people Numb. 1. when the Princes here employed in the offerings were first constituted; and after the disposal of the Tribes about the Tabernacle, the order of which is here observed in the time of their offerings.
