On the seventh:

Both Jewish and Christian writers have been surprised that this work of offering went forward on the seventh day (which they suppose to have been a sabbath), as well as on the other days. But:

1. There is no absolute proof that this seventh day of offering was a sabbath.
2. Were it even so, could the people be better employed than in thus consecrating themselves and their services to the Lord?
We have already seen that every act was a religious act; and we may rest assured, that no day was too holy for the performance of such acts as are here recorded. Here it may be observed, that Moses has thought fit to set down distinctly, and at full length, the offerings of the princes of each tribe, though, as we have already observed, they were the very same, both in quantity and quality, that an honourable mention might be made of every one apart, and that none might think himself in the least neglected.
