Amos was a prophet during the reign of Jeroboam ben Joash (Jeroboam II), ruler of Israel from 753 BCE to 793 BCE, and the reign of Uzziah, King of Judah, at a time when both kingdoms (Israel in the North and Judah in the South) were peaking in prosperity. He was a contemporary of the prophet Hosea, but likely preceded him. Many of the earlier accounts of prophets found in the Old Testament are found within the context of other accounts of Israel's history. Amos, however, is the first prophet whose name also serves as the title of the corresponding biblical book in which his story is found.
Time When Written
Most scholars believe that Amos gave his message in the autumn of 750 BC or 749 BC. It is generally understood that his preaching at Bethel lasted only a single day at the least and a few days at the most. Leading up to this time, Assyrian armies battled against Damascus for a number of years, which greatly diminished Syria's threat to Israel. As a result of the fighting amongst its neighbors, Israel had the benefit of increasing its borders almost to those of the time of kings David and Solomon.
