Samuel, grown old, testifies his integrity before the people, which they confirm, Sa1 12:1-5. He reproves them for their ingratitude and disobedience; and gives a summary of the history of their fathers, Sa1 12:6-12. He exhorts them to future obedience, and calls for a sign from heaven to confirm his authority, and to show them their disobedience: God sends an extraordinary thunder and rain, Sa1 12:13-19. He warns them against idolatry, and exhorts to obedience, and promises to intercede for them, Sa1 12:20-23. Sums up their duty, and concludes with a solemn warning, Sa1 12:24, Sa1 12:25.
