The Assyrians would be taken captive; now God addresses the prophet in the familiar language of the Scriptures, likening the quiet waters of Siloam in Jerusalem to the mighty river of Assyria. He states that this river will inundate the entire land of Israel with its powerful waves, breaching its banks and surging forth so violently that it will flood the territory of the ten tribes and extend into Judah, reaching up to the neck. This indicates imminent captivity; although Judah had not yet been captured, all the cities of the two tribes had fallen, with only Jerusalem spared by the immense mercy of God.
Moreover, the strength of the king of Assyria and his countless army, symbolized by the flood, is described through another analogy—its wings, representing leaders and a vast multitude, will cover the land of Immanuel, meaning God with us, yet it will not conquer it. Though the term Immanuel in the Septuagint pertains to the following verse and is not named as in the Hebrew, it signifies God's presence. Siloam, located at the base of Mount Zion, is not constantly filled but flows forth at specific times and days, rushing noisily through the terrain's irregularities. This is well known, especially among us who live in this region. The implication is that the ten tribes preferred subservience to Racine and the son of Romelia—the kings of Damascus and Samaria—over the lineage of David, which was established by divine will. Therefore, I will allow them to be enslaved, not by these kings they chose, but by the king of Assyria, whose dominance over Samaria is likened to the overwhelming flood of a river. An appeal is made to Immanuel, indicating that the king of Assyria has grown so bold as to try to possess the land of Judah as well.
In a sacramental sense, any heretic who relies on secular wisdom to seize Jerusalem—the Church—while neglecting the waters of Siloam, which symbolizes being sent and the path to eternal life, will find himself betrayed to Assyria’s leader and plunged into the depth of his sins. Such arrogance leads him to tempt the Savior by presenting all the earthly kingdoms, proclaiming, “all these have been given to me” (Luke 4). He will strive to infiltrate Judas, symbolizing the house of confession, frequently reaching the neck of the negligent within the Church, seeking to ensnare believers in Christ, spreading his wings to cover all of Immanuel's territory. However, he will ultimately be unable to possess it, as God is present within Judas.
In the Gospel of John, it is stated that the Lord sent a man who was blind from birth, whose eyes He anointed with mud made from His saliva, to the waters of Siloam. After washing off the mud, the blind man received his sight. This remarkable act illustrates that the blindness of the Jews, and of all unbelievers, can only be healed when the darkness of past errors is dispelled by the teachings of the waters of Christ, flowing gently without the disturbance of elaborate words. The phrase in the Septuagint about overtaking every wall of Judah and stripping it of those capable of lifting their heads is not present in the Hebrew text and is marked in the Greek codices with a crushing horn.
