1 Samuel 15:31 - Joseph Benson’s Commentary on the Old and New Testaments

So Samuel turned again 1st, That the people might not, upon pretence of this sentence of rejection, withdraw their obedience from their sovereign; whereby they would both have sinned against God, and have been as sheep without a shepherd. 2d, That he might rectify Saul's error, and execute God's judgment upon Agag.
