Amos (prophet) in the context of "Book of Amos"

The Book of Amos is the third of the Twelve Minor Prophets in the Christian Old Testament and Jewish Tanakh and the second in the Greek Septuagint. The Book of Amos has nine chapters. According to the Bible, Amos was an older contemporary of Hosea and Isaiah, and was active c. 750 BC during the reign of Jeroboam II (788–747 BC) of Samaria (Northern Israel), while Uzziah was King of Judah. Amos is said to have lived in the kingdom of Judah but preached in the northern Kingdom of Israel where themes of social justice, God's omnipotence, and divine judgment became staples of prophecy. In recent years, scholars have grown more skeptical of The Book of Amos’ presentation of Amos’ biography and background. It is known for its distinct “sinister tone and violent portrayal of God.”
