Biblical Context:
The prophecy against the ruler of Tyre is found in the book of Ezekiel, specifically in Ezekiel 28:1-10. This passage is part of a series of oracles against various nations and their leaders, delivered by the prophet Ezekiel during the Babylonian exile. Tyre was a prominent Phoenician city-state known for its wealth, maritime prowess, and strategic location on the Mediterranean coast.

Historical Background:
Tyre was a significant commercial hub in the ancient Near East, renowned for its trade networks and skilled artisans. The city was divided into two parts: the mainland settlement and the island city. Its rulers were often seen as powerful and influential figures due to Tyre's economic strength and political alliances. During Ezekiel's time, Tyre was at the height of its prosperity, which led to pride and a sense of invincibility among its leaders.

Prophetic Message:
The prophecy against the ruler of Tyre is a divine pronouncement of judgment due to the ruler's arrogance and self-deification. The ruler is accused of claiming to be a god, sitting on the throne of a god, and possessing wisdom and understanding that rival divine attributes. This hubris is seen as an affront to the sovereignty of the true God, Yahweh.

Key Verses:
Ezekiel 28:2-5 states: "Son of man, say to the ruler of Tyre that this is what the Lord GOD says: 'In the pride of your heart you say, "I am a god; I sit on the throne of a god in the heart of the sea." But you are a man and not a god, though you regard your heart as the heart of a god. Behold, you are wiser than Daniel; no secret is hidden from you! By your wisdom and understanding you have gained your wealth and amassed gold and silver for your treasuries.'"

Themes and Symbolism:
1. Pride and Hubris: The ruler's claim to divinity is a central theme, highlighting the dangers of pride and self-exaltation. This mirrors the broader biblical narrative that emphasizes humility before God.

2. Divine Judgment: The prophecy underscores the inevitability of divine judgment against those who elevate themselves above God. The ruler's downfall is portrayed as a direct consequence of his arrogance.

3. Wisdom and Wealth: The passage acknowledges the ruler's wisdom and wealth, yet these attributes are ultimately seen as insufficient to save him from God's judgment. This serves as a reminder of the limitations of human achievement without divine favor.

4. Mortality: Despite his claims, the ruler is reminded of his mortality. Ezekiel 28:9 states: "Will you still say, 'I am a god,' in the presence of those who slay you? You will be only a man, not a god, in the hands of those who wound you."

Outcome:
The prophecy foretells the ruler's demise at the hands of foreign invaders, a fate that serves as a testament to the sovereignty of God over all nations and rulers. The ruler's death is depicted as a humbling event, stripping away his pretensions of divinity and exposing his humanity.

Theological Implications:
The prophecy against the ruler of Tyre serves as a cautionary tale about the perils of pride and the ultimate authority of God over human affairs. It reinforces the biblical theme that no earthly power can withstand the judgment of God, and it calls for recognition of God's supremacy in all aspects of life.
