Leviticus 11:1

From the laws concerning the priests, he now comes to those which belong to all the people. God spake to both of them, because the cognizance of the following matters belonged to both: the priest was to direct the people about the things forbidden or allowed, where any doubt or difficulty arose; and the magistrate was to see the direction followed.

Yahweh speaks to Moses and Aaron conjointly. (Compare Lev 13:1; Lev 15:1.) The high priest, in regard to the legal purifications, is treated as co-ordinate with the legislator.

And the Lord spake unto Moses - In the preceding chapter the priests are expressly forbidden to drink wine; and the reason for this law is given also, that they might be able at all times to distinguish between clean and unclean, and be qualified to teach the children of Israel all the statutes which the Lord had spoken, Lev 10:10, Lev 10:11; for as inebriation unfits a person for the regular performance of every function of life, it must be especially sinful in those who minister in holy things, and to whom the teaching of the ignorant, and the cure of souls in general, are entrusted. Scheuchzer has remarked that no Christian state has made any civil law against drunkenness, (he must only mean the German states, for we have several acts of parliament against it in England), and that it is only punished by contempt. “Custom,” says he, “that tyrant of the human race, not only permits it, but in some sort authorizes the practice, insomuch that we see priests and ministers of the Church ascend the pulpit in a state of intoxication, judges seat themselves upon the benches, physicians attend their patients, and others attempt to perform the different avocations of life, in the same disgraceful state.” - Physic. Sacr., vol. iii., p. 64. This is a horrible picture of German manners; and while we deplore the extensive ravages made by this vice, and the disgrace with which its votaries are overwhelmed, we have reason to thank God that it very rarely has ever appeared in the pulpit, and perhaps was never once seen upon the bench, in our own country. Having delivered the law against drinking wine, Moses proceeds to deliver a series of ordinances, all well calculated to prevent the Israelites from mixing with the surrounding nations, and consequently from being contaminated by their idolatry. In Leviticus 11 he treats of unclean Meats. […]
