Wrote it in a book. — The “Law of the Kingdom,” which Samuel rehearsed before the people, and which he wrote in a roll, and laid solemnly up and preserved among the State archives, related to the divinely established right and duties of the God-appointed king, and also clearly set forth the limitations of his power. The vice-gerent on earth of the invisible King could be no arbitrary despot, unless he transgressed plainly and openly the “manner of the kingdom” written in a book, and laid up before the Lord by Samuel.
This sacred document, we may assume, contained, too, the exact details of the singular story of the choice of the first king of Israel. It was well, no doubt, thought Samuel, that coming ages should know exactly how it came to pass that he, the seer, anointed the Benjamite of Gibeah as king over the Lord’s inheritance. We may, therefore, fairly conclude that from the record laid up among the sacred archives in the sanctuary, the compiler or redactor of this “Book of Samuel” derived his intimate knowledge of every little fact connected with the Divine choice of Saul.
The legal portion of this writing respecting the kingdom was, of course, strictly based upon what Moses had already written on this subject in Deuteronomy (see 1 Samuel 17:14-20).
We find here, in this writing of Samuel, the first trace of literary composition among the Israelites since the days of Moses. The great revival in letters which began shortly after the days of Saul was due, most probably, to the influence of Samuel and those great schools of the prophets which he had established in the land.
And laid it up before the Lord. — We are not told where this was done, but the words seem to imply that the document, or roll, was placed by the side of the Ark, then in the “city of woods,” Kiriath-yearim. Josephus says this writing was preserved in the Tabernacle of the Holy of Holies, where the Book of the Law had been laid up (Deuteronomy 31:26).
And Samuel sent all the people away. — It is noteworthy that even after the formal popular ratification of Saul’s election as king, it is Samuel who dismisses the assembly. Indeed, throughout the remainder of the great seer’s life, whenever he appears on the scene, he is evidently the principal person, occupying a position above king or priest. On the other hand, after this period Samuel made but comparatively few public appearances; of his own free will he seems to have retired into privacy, and only in emergencies to have left his retirement.
