After another pass at II King 16 & 17 and II Chronicles 27 & 28, Israel has fallen and has been hauled away. God has orchestrated a priest to come back and teach His ways, but the people just add that to their previous worship. Meanwhile Judah is still alive, but not thriving under Ahaz. Both book passages end with the death of Ahaz and the introduction of his successor, his son Hezekiah.
Now the Blue Letter Bible chronological reading list sends us back to Isaiah. Previously in Isaiah, he was prophesying about the end of Israel and two beautiful chapters about the Messiah.
Micah has brought the bad news of Judah's fall and captivity and the message of its deliverance through a remnant spared by the Lord; but now we're looking forward to the last days when the nations come together to try and crush Israel; but are destroyed by the Lord.
According to the NASB Ryrie Study Bible organization, Chapters 3 and 4 combine in a sub section titled, A Message of Doom and Deliverance. There was much doom in Chapter Three. Bring on the deliverance!
The close of Chapter 11 of Isaiah is a prophesy that the remnant of Israel will pour out of Assyria like a highway, the second exodus. This will be paralleled in the Millennial Kingdom as God calls forth the dispersed Jews to be his Royal Priesthood. Chapter 12 picks up there.
Amos had his first three visions and a confrontation with the high priest at Bethel, the king's high priest, since Israel has made their own choose-your-own religion. The priest, Amaziah, tried to get the king to kill Amos by cherry-picking from Amos. It ended up costing Amaziah, literally, everything.
