*Note that the order of the three major prophets in the Masoretic text is Isaiah, Jeremiah, Ezekiel. The Talmud here refers to a different ordering (and gives reasoning for it later in this passage).
(1) The word of the LORD that came to Hosea son of Beeri, in the reigns of Kings Uzziah, Jotham, Ahaz, and Hezekiah of Judah, and in the reign of King Jeroboam son of Joash of Israel. (2) When the LORD first spoke to Hosea, the LORD said to Hosea, “Go, get yourself a wife of whoredom and children of whoredom; for the land will stray from following the LORD.” (3) So he went and married Gomer daughter of Diblaim. She conceived and bore him a son, (4) and the LORD instructed him, “Name him Jezreel; for, I will soon punish the House of Jehu for the bloody deeds at Jezreel and put an end to the monarchy of the House of Israel. (5) In that day, I will break the bow of Israel in the Valley of Jezreel.” (6) She conceived again and bore a daughter; and He said to him, “Name her Lo-ruhamah; for I will no longer accept the House of Israel or pardon them. (7) (But I will accept the House of Judah. And I will give them victory through the LORD their God; I will not give them victory with bow and sword and battle, by horses and riders.)” (8) After weaning Lo-ruhamah, she conceived and bore a son. (9) Then He said, “Name him Lo-ammi; for you are not My people, and I will not be your [God].”
The list of Kings of Israel and Judah put the prophet's career in early to mid 8th century B.C.E. He was a contemporary of Amos and Isaiah (from the opening 39 chapters of the Book of Isaiah).
(1) The word of the LORD that came to Joel son of Pethuel.
Unlike some other book of the Prophets the superscription does not give us evidence of the dating of Joel's prophetic career. Many Biblical scholars date the book later while Tradition place the book among the earlier of the so-called Minor Prophets.

(1) The words of Amos, a sheepbreeder from Tekoa, who prophesied concerning Israel in the reigns of Kings Uzziah of Judah and Jeroboam son of Joash of Israel, two years before the earthquake.
The earthquake mentioned is generally linked to a quake from around 760 B.C.E attested to in archaeological evidence. This would put his career contemporary with Hosea and Isaiah. The structure of the book is threefold: 1) oracles of doom against foreign nations; 2) oracles of doom against Judah and Israel; and 3) oracles of hope referring to Israel and the Davidic monarchy.
