As the Assyrian army sweeps through the land, capturing the fortified cities of Judah, a grave threat hangs over Jerusalem. To save his kingdom from destruction, King Hezekiah decides to take a diplomatic step and surrender. He sends a delegation to the King of Assyria, who has set up his military base in Lachish, a captured Judean fortress.
In his message, Hezekiah offers a total surrender, openly admitting his fault. The primary approach among commentators is that this admission is a direct acknowledgment of his previous rebellion; he confesses that he was wrong to stop serving the Assyrian king. Following this confession, Hezekiah begs the king to halt the attack and pull his forces back from the land. To appease the foreign ruler, he declares his absolute willingness to accept any punishment, harsh decree, or financial penalty imposed upon him. Taking him at his word, the King of Assyria demands a massive fine of three hundred talents of silver and thirty talents of gold.
[רד״ק] provides the broader historical context for this exchange, explaining that paying this heavy fine successfully bought a temporary peace and caused the Assyrian army to withdraw. However, this quiet period did not last. Sometime later, Hezekiah stopped paying the annual tribute to Assyria. In response, the Assyrian forces returned to besiege and threaten Jerusalem. This renewed conflict ultimately ended only when the massive Assyrian camp was defeated in a single night by an angel of God.
