Amos was a herdsman who lived in the village of Tekoa, before becoming a prophet during the reign of King Uzziah. Amos was not the first Bible prophet, but he was the first prophet to have his prophecies recorded in a separate book of the Bible, that being the book of Amos.
Amos prophesied about 760 BC during the reigns of King Uzziah of Judah, and Jeroboam II of Israel. He left Judah and went to Israel. He had a short ministry. Amos predicted the overthrow of Israel by the Assyrians. Historical hindsight shows us that roughly 30 years after Amos’ prophecy the Assyrians took the northern tribes into captivity (721 to 718 B.C.). At that time Israel ceased to function as a sovereign nation. He and also predicted the doom of Judah, and the doom of the surrounding nations (Syria, Gaza, Ammon and Moab) nations that anciently bordered Israel and Judah—and whose descendants remain in that general area even today.
In his prophecies against Israel, Amos spoke of the social sins of the day, such as greed, corruption, false worship, and injustice. His book ends with a scant hope that the people of Israel would listen and heed the warnings. But subsequent events sadly proved that the house of Israel paid little attention either to Amos or to the contemporary Hebrew prophet Hosea, also divinely sent to warn the country.
Hope this helps.
