Jamieson, Fausset and Brown on 1 Samuel 11:12-15

12-15. the people said ..., Who is he that said, Shall Saul reign over us?--The enthusiastic admiration of the people, under the impulse of grateful and generous feelings, would have dealt summary vengeance on the minority who opposed Saul, had not he, either from principle or policy, shown himself as great in clemency as in valor. The calm and sagacious counsel of Samuel directed the popular feelings into a right channel, by appointing a general assembly of the militia, the really effective force of the nation, at Gilgal, where, amid great pomp and religious solemnities, the victorious leader was confirmed in his kingdom [1Sa 11:15].
