Amos the ProphetAmos - Another of the minor prophets.  Unlike Joel, however, Amos clearly states when he lived:

 

"The words of Amos, who was among the sheepherders from Tekoa, which he envisioned in visions concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam son of Joash, king of Israel, two years before the earthquake." (Amos 1:1, NASB)
