Israel said to the prophet Samuel, “Appoint for us a king to
judge us like all the nations.” They were looking for a judge and a defender, someone who would grant them justice against their domestic enemies and take up
arms against foreign enemies on their behalf. Instead, in Saul, after an
initial honeymoon period, they got a king who judged them arbitrarily,
oppressively, selfishly and moodily, and who fought on their behalf with only
limited success.
Exactly like all the nations.
