Deuteronomy 17:14

When thou art come unto the land , etc. This phraseology, which is common to the laws which respect the affairs of the Hebrews after they should be settled in Canaan, implies that this law was given whilst they were yet outside the Promised Land. It is plain also, from the tenor of the whole statement in this verse, that the legislator in this case is providing for what he supposes may happen, is likely to happen, but which he by no means desires should happen. Moses foresaw that the people would wish to be as the nations around them—governed by a king—and he legislates accordingly, without approving of that wish.
