When the elders come to Samuel at Ramah and ask for a king to judge them like all the nations, the reason they give is that his own sons take bribes and pervert judgment, which is awkward, because it is true. He is displeased and prays, and is told that the people have not rejected him but God, and to warn them and then do as they ask.
The warning is a description of a state. A king will take your sons for his chariots and to run before them, and to plough his ground and reap his harvest and make his weapons. He will take your daughters to be perfumers, cooks and bakers. He will take your fields and vineyards and olive groves, the best of them, and give them to his servants. He will take a tenth of your seed and of your flocks, and you shall be his servants, and you shall cry out in that day because of the king you have chosen, and God will not hear you.
It is a list of taxation, conscription and land seizure, delivered before any of it happens, and everything in it is enacted in the books that follow.
Readers have long noticed that the books of Samuel contain both this and passages that treat the monarchy as a gift, and there are three separate accounts of how Saul was made king. Critical scholarship generally reads the material as combining sources with different attitudes to kingship. The editors did not smooth them out, and the result is a founding narrative for the monarchy that carries its own most damaging objection inside it.
