What does 1 Samuel 8:11 mean?
The Lord has told Samuel to allow the people to have a human king (1 Samuel 8:4–5) with one stipulation. Samuel must give them a formal warning—a legal disclaimer—about how kings will carry out their rule. The ways of the king, and the legal rights he will have, amount to what it will cost the people to live under his rule.Samuel begins by declaring that what follows will be the "ways" or "rights" or "practice" of Israel's king. This does not necessarily mean these are the rights given to the king by God. However, they are the nature of being ruled by a single person. They are the patterns demonstrated by many kings of city-states and nations during this era. Israel should know this, as they are asking to be like these other cultures.
For starters, the Israelites should expect the king to build a "standing army:" a permanent military. This will eventually be equipped with chariots. The Israelites had never had chariots before this time, but King David would begin to use them (2 Samuel 8:4) and Solomon would fully employ them for regular use (1 Kings 4:26). One of the stipulations for kings in the Mosaic law was that they not "acquire many horses for himself or cause the people to return to Egypt in order to acquire many horses" (Deuteronomy 17:16).
The use of chariots requires the care and feeding of horses, as well as chariot riders and even men to run before the king's chariots to announce that the king was approaching (2 Samuel 15:1; 1 Kings 1:5). These chariot soldiers will be plucked from Israel's youth, Samuel warns.
