OT prophets (Amos, Jonah) judged Gentile nations on moral grounds, not Mosaic Law violations

When Old Testament prophets like Amos addressed Gentile nations (Amos 1–2), they judged them for abusing people and failing basic moral duties—not for breaking Mosaic commandments. When Amos turns to Israel, the charges shift to specific violations of God's commandments. This confirms a two-tier accountability structure: moral law for Gentiles, Mosaic Law specifically for Israel.
