The words of Amos, who was among the herdsmen of Tekoa, which he saw concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash king of Israel, two years before the earthquake.
The six nations previously mentioned did not have God’s law so they are not condemned by that law. They are condemned for ignoring the knowledge of right and wrong that God has put in the hearts of all people. Their inhumanity and cruelty are inexcusable (cf. Romans 2:12-15). But Judah did have God’s law. It is condemned for disobeying that law and going its own way (4-5).
