The manner of the kingdom - i. e., the just prerogative of the kingdom, the law, or bill of rights, by which the king’s power was limited as well as secured. It is not improbable that what Samuel wrote was simply a transcript of Deuteronomy 17:14-20, which he “laid up before the Lord,” i. e., placed by the side of the ark of the covenant with the copy of the Law (see Deuteronomy 31:26). It would be ready for reference if either king or people violated the “law of the kingdom.”
