Josiah was a king of Judah who began to reign at the age of eight. He followed God and reformed the nation by destroying idols and restoring the temple. His mistake was confronting the Pharaoh of Egypt without God’s guidance, which led to his death in battle. His legacy was bringing the people back to faith in God, and he is remembered as a righteous and faithful king.
After the death of his father, King Amon, Josiah became king when he was only eight years old. His story is found mainly in 2 Kings chapters 22–23 and 2 Chronicles chapters 34–35. Josiah lived at a time when the people of Judah had turned away from God, worshiping idols and living in sin. Even as a young boy, Josiah sought the Lord with all his heart and became one of the most faithful kings in Judah’s history.
At the age of sixteen, Josiah began to seek God earnestly, and at twenty, he initiated a spiritual reform: he destroyed pagan altars, idol images, and places of false worship. Later, during the restoration of the temple, the priests found the “Book of the Law” (probably the book of Deuteronomy). When Josiah heard the words of the law, he was deeply grieved by the sins of the people and determined to obey everything God had commanded.
He gathered the people, read the Book of the Law publicly, and renewed the covenant with God. He also celebrated the Passover as it had not been observed for a long time, showing great zeal for obedience to God’s will.
However, at the end of his life, Josiah made a mistake: he confronted Pharaoh Neco of Egypt in battle without God’s direction. He was mortally wounded in the battle on the plain of Megiddo and died at the age of thirty-nine.

Josiah’s legacy was one of faithfulness, obedience, and spiritual reform. The Bible describes him as a king who followed God with all his heart, soul, and strength. His example teaches the importance of seeking God early in life, obeying His Word, and not acting on impulse, but always seeking His direction.

Bible Study on King Josiah
Why was Josiah considered the best king?
Josiah was considered one of Judah’s best kings because of his faithfulness, obedience, and zeal in seeking the Lord with all his heart. The Bible states:
Neither before nor after Josiah was there a king like him who turned to the Lord as he did with all his heart and with all his soul and with all his strength, in accordance with all the Law of Moses.
- 2 Kings 23:25
Even though he began to reign at only eight years old, Josiah showed from an early age a heart inclined toward God. At sixteen, he began to seek the Lord earnestly, and at twenty, he launched a great religious reform, destroying idols and pagan worship sites.
The high point of his reign was the discovery of the Book of the Law in the temple (2 Kings 22:8). When he heard God’s Word, Josiah deeply repented and led the people to renew their covenant with the Lord (2 Kings 23:1–3). He also celebrated a Passover unlike any seen for centuries (2 Chronicles 35:18).
Josiah is remembered as an example of repentance, reform, and faithfulness, showing that it is possible to follow God even in times of corruption and idolatry.
What was King Josiah’s sin?
The Bible does not record a direct moral sin committed by Josiah, such as idolatry or injustice, but it does highlight one significant mistake: he confronted Pharaoh Neco of Egypt without seeking God’s guidance.
Neco warned him that the war was not against Judah and that God had sent him (2 Chronicles 35:20–22). Even so, Josiah disguised himself and entered battle, disobeying divine direction. This act of presumption and lack of discernment led to his death in the battle of Megiddo.
Although he was a faithful king, this mistake showed the importance of always seeking God’s will before acting. The Bible makes it clear that despite his tragic end, Josiah was remembered as a righteous king, devoted to obeying God’s law.
Who Destroyed the Temple That Josiah Restored?
The temple that King Josiah restored was destroyed years later by the Babylonians under King Nebuchadnezzar. After Josiah’s death, his sons and grandsons reigned in Judah, but most of them did what was evil in the sight of the Lord. The people returned to idolatry and disobedience, ignoring the warnings of the prophets, such as Jeremiah.
Because of the people’s continual rebellion, God allowed the Babylonian Empire to invade Jerusalem. Nebuchadnezzar besieged the city, destroyed its walls, burned the temple, and took many Jews captive to Babylon. The temple that had been zealously restored by Josiah was completely plundered and reduced to ruins.
This event marked the end of the kingdom of Judah and the beginning of the Babylonian exile, fulfilling the prophecies announced by Jeremiah and other prophets. The destruction of the temple symbolized God’s judgment on a people who rejected His covenant, even after the efforts of faithful kings like Josiah.
Nevertheless, God promised restoration, and decades later, the Jews returned from exile and rebuilt the temple under the leadership of Zerubbabel, as recorded in the books of Ezra and Haggai.
Why Did King Josiah Die?
King Josiah died because he decided to confront Pharaoh Neco of Egypt, who was passing through Judah on his way to Assyria. Even after Neco warned him that God had sent him and that his mission was not against Judah, Josiah ignored the message and went into battle. Disguised, he was struck by arrows in the battle of Megiddo and died.
Josiah made the mistake of not seeking God’s direction before acting. Despite his lifelong faithfulness, that impulsive decision led to his premature death at the age of 39.
What We Learn from King Josiah
The life story of King Josiah teaches us lessons about faith, obedience, and repentance. Even at a young age, Josiah showed that age is no barrier to seeking God. At sixteen, he began to seek the Lord earnestly, and at twenty, he started a great reform in Judah, destroying idols and restoring true worship. His actions demonstrated courage and commitment to the truth, even in a corrupt society.
When the Book of the Law was found in the temple, Josiah was deeply moved by how far the people had strayed from God. He responded with humility, repentance, and decisive action, gathering all the people to renew their covenant with the Lord. His reaction to God’s Word teaches us the importance of sincere repentance and a desire to obey God’s will.
His death also carries an important lesson: even the faithful must seek God’s guidance before making decisions. Josiah went to war without consulting the Lord, ignoring Pharaoh Neco’s warning, and died as a result. Josiah left behind a legacy of faith, reform, and zeal for the truth. His example challenges us to seek God sincerely and act with wisdom.
