SAMUEL WAS A COMBINATION PROPHET, judge, and one-man band. When the old curmudgeon wasn't out in the field trying to fight off the Philistine guerrillas, he was riding his circuit trying to keep the tribes of Israel honest, and when he wasn't doing that, he was giving them hell for cheating on Yahweh every time a new fertility god showed up with a come-hither look in his eye. When he reached retirement age, he might have turned things over to his sons, but they were a bunch of crooks who sold justice to the highest bidder, and the Israelites said maybe he'd better get them a king instead. They'd never had one before, but they felt the time had come. Samuel threw a fit.
He said there was only one king worth the time of day, and Yahweh was his name. He also told them kings were a bad lot from the word go and didn't spare them a single sordid detail. They were always either drafting you into their armies or strong-arming you into taking care of their farms. They took your daughters and put them to work in their kitchens and perfume factories. They filled their barns with your livestock and got you to slave for them till you dropped in your tracks. What was more, if the Israelites chose a king, Yahweh would wash his hands of them and good riddance. Samuel had it on the highest authority. But the Israelites insisted, and since Samuel didn't have the pep he'd once had, he finally gave in.
The king he dug up for them was a tall drink of water named Saul. He was too handsome for his own good, had a rich father, and when it came to religion tended to go off the deep end. Samuel had him in for a meal and, after explaining the job to him, anointed him with holy oil against his better judgment and made him the first king Israel ever had. He regretted this action till the day he died, and even in his grave the memory of it never gave him a moment's peace.
