The Bible verse 2 Chronicles 21:18 in the King James Version (KJV) states: "And after all this the Lord smote him in his bowels with an incurable disease."This verse is part of the narrative in the Book of 2 Chronicles, which focuses on the history of the kings of Judah. In this particular verse, the "him" being referred to is King Jehoram, the son of King Jehoshaphat. The verse is part of a larger passage that recounts the reign of King Jehoram and the punishment he received from the Lord.

The context of this verse is important for understanding its meaning and significance. King Jehoram is depicted as a wicked ruler who led the people of Judah astray. He married a daughter of King Ahab of Israel, a woman named Athaliah, and he followed the wicked ways of the northern kingdom of Israel, including idol worship and the abandonment of the worship of the true God. King Jehoram also led the people of Judah to engage in ungodly practices, such as the sacrificing of his own brothers and other influential leaders in the kingdom. These actions provoked the anger of the Lord, and as a result, the Lord smote him with an incurable disease.

One of the themes present in this verse and the larger passage is the notion of divine judgment and the consequences of disobedience. Throughout the Bible, there are numerous instances where individuals or nations face the consequences of their sinful actions. In the case of King Jehoram, his disobedience and unfaithfulness to the Lord led to the divine punishment of an incurable disease. This theme serves as a reminder of the importance of obedience and faithfulness to God's commands and the consequences of straying from His will.

The symbolism within this verse is also worth noting. The smiting of King Jehoram with an incurable disease can be seen as a symbol of the spiritual sickness and decay that resulted from his sinful actions. It serves as a grim reminder of the destructive nature of sin and the consequences it brings upon those who engage in it. The disease serves as a physical manifestation of the spiritual corruption that had taken root in King Jehoram's heart and the kingdom of Judah under his rule.

Additionally, this verse also highlights the sovereignty and power of the Lord. The infliction of an incurable disease demonstrates the Lord's ability to bring judgment and punishment upon those who rebel against Him. It underscores the idea that ultimately, God is in control and His will shall be done, regardless of the actions of individuals or nations. This serves as a reminder of the importance of living in reverence and obedience to the Lord.

In conclusion, 2 Chronicles 21:18 in the King James Version (KJV) is a powerful and sobering verse that carries deep thematic, contextual, and symbolic significance. It serves as a stark reminder of the consequences of disobedience, the sovereignty of God, and the spiritual decay that results from sin. The verse encourages readers to reflect on the importance of obedience to God and the destructive nature of sin. It stands as a testament to the righteousness and justice of the Lord, and a warning of the consequences of turning away from His will.
