After asking for a king Samuel goes on to numerate the rights the king will demand from the Israelites
KJV 1 Samuel 8 : 10 - 17
And Samuel told all the words of the LORD unto the people that asked of him a king. 11 And he said, This will be the manner of the king that shall reign over you: He will take your sons, and appoint them for himself, for his chariots, and to be his horsemen; and some shall run before his chariots. 12 And he will appoint him captains over thousands, and captains over fifties; and will set them to ear his ground, and to reap his harvest, and to make his instruments of war, and instruments of his chariots. 13 And he will take your daughters to be confectionaries, and to be cooks, and to be bakers. 14 And he will take your fields, and your vineyards, and your oliveyards, even the best of them, and give them to his servants. 15 And he will take the tenth of your seed, and of your vineyards, and give to his officers, and to his servants. 16 And he will take your menservants, and your maidservants, and your goodliest young men, and your asses, and put them to his work. 17 He will take the tenth of your sheep: and ye shall be his servants.
I don't know whether I have missed it but there seems to be no record of the immediate king(Saul) ever claiming those rights other than the misdemeanours stated below
Threatening the Israelites to join his army
KJV 1 Samuel 11 : 7
And he took a yoke of oxen, and hewed them in pieces, and sent them throughout all the coasts of Israel by the hands of messengers, saying, Whosoever cometh not forth after Saul and after Samuel, so shall it be done unto his oxen. And the fear of the LORD fell on the people, and they came out with one consent.
Unsanctioned sacrifice
KJV 1 Samuel 13 : 9
And Saul said, Bring hither a burnt offering to me, and peace offerings. And he offered the burnt offering.
Forbidding soldiers to eat
KJV 1 Samuel 14 : 24
And the men of Israel were distressed that day: for Saul had adjured the people, saying, Cursed be the man that eateth any food until evening, that I may be avenged on mine enemies. So none of the people tasted any food.
Failure to obey God in the Amalekite debacle
KJV 1 Samuel 15 : 9
But Saul and the people spared Agag, and the best of the sheep, and of the oxen, and of the fatlings, and the lambs, and all that was good, and would not utterly destroy them: but every thing that was vile and refuse, that they destroyed utterly.
Trying to kill David
KJV 1 Samuel 19 : 1
And Saul spake to Jonathan his son, and to all his servants, that they should kill David.
Other than these unfortunate Incidents there is nowhere Saul claimed the rights resembling what Samuel had numerated in the above texts
Was Samuel referring to Saul?
