Isaiah 22:14 And it was revealed in mine ears by the LORD of hosts, Surely this iniquity shall not be purged from you till ye die, saith the Lord GOD of hosts.
In this verse The LORD was pronouncing the death penalty on Jerusalem and Judah - God declared the only way to end their iniquity was through death. Under the Chileans (Babylon) Judah was scattered and Jerusalem was plundered and broken down. For all practical purposes as a nation and city they died - became desolate.

The coming Woes in Chapters 28-33 is the announcement: that this death could not be avoided. The LORD had declared the death penalty upon His people.

God’s law concerning the death penalty

Deuteronomy 17:6  (concerned offering blemished sacrifice, worshiping / serving other gods}

Deuteronomy 19:15  (concerning sinning)

John 8:17

Hebrews 10:28 A

***God's law is clear - No one could be condemned by the witness of one man. Only when the testimony of two or three witnesses agreed could the death penalty for disobeying God's law be pronounced.

***Could God pronounce the death penalty upon Jerusalem and Judah with only one witness? Could God ignore His Law? ( The answer of course is NO!)

God uses His own advice - Follows His own laws

Isaiah 1:1  The vision of Isaiah the son of Amoz, which he saw concerning Judah and Jerusalem in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah

Micah 1:1  The word of the LORD that came to Micah the Morasthite in the days of Jotham, Ahaz, and Hezekiah, kings of Judah, which he saw concerning Samaria and Jerusalem

Hosea 1:1 The word of the LORD that came unto Hosea, the son of Beeri, in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah, and in the days of Jeroboam the son of Joash, king of Israel.

Three Prophets serving The LORD during the same period of history, in complete agreement with one another. All three ignored by the nation - Hebrews 10:28 Anyone who has rejected Moses' law dies without mercy on the testimony of two or three witnesses.

Judah and Jerusalem chose to believe false prophets instead of believing God’s prophets -multiple witnesses speaking the same message- believe God and obey His voice (the prophets) and you will be established. Judgment is coming if you do not believe you will not be established.

Read Matthew 22:1-8 This parable first is about Jesus first coming to Israel. It also sums up Israel's relationship wit The LORD through the prophets

God could not overlook the sins of Judah any longer. Justice demanded their death thus Isaiah 22:14

God could not overlook the sins of Judah any longer. Justice demanded their death - God’s promise to His people there is life after death.

God was not through with Israel than - He is not through with Israel today - Israel is still spiritually dead today - God’s promise there is life after death.
