Jehoshaphat, the son of Asa, was the fourth king of the Kingdom of Judah, reigning from approximately 873 to 849 BC. His reign is noted for religious reforms, military fortifications, and a commitment to seeking the Lord, distinguishing him as one of the more righteous kings in Judah's history. The primary biblical accounts of Jehoshaphat's reign are found in 1 Kings 22 and 2 Chronicles 17-20.

Early Reign and Religious Reforms

Jehoshaphat ascended to the throne following the death of his father, Asa. He is commended for walking "in the ways of his father David" and not seeking the Baals (2 Chronicles 17:3-4). His early reign was marked by a series of religious reforms aimed at purifying the worship practices in Judah. He removed the high places and Asherah poles, which were associated with idolatrous worship, and sent officials, Levites, and priests throughout the land to teach the people from the Book of the Law of the Lord (2 Chronicles 17:6-9).

Military Strength and Alliances

Jehoshaphat fortified the cities of Judah and maintained a strong military presence, which included a large and well-equipped army. The Lord established his kingdom, and the fear of the Lord fell upon the surrounding nations, preventing them from waging war against Judah (2 Chronicles 17:10). Despite his military strength, Jehoshaphat sought alliances to secure peace, notably with the northern Kingdom of Israel. He formed a marriage alliance with King Ahab by marrying his son Jehoram to Ahab's daughter Athaliah (2 Chronicles 18:1).

Alliance with Ahab and the Battle of Ramoth-gilead

Jehoshaphat's alliance with Ahab led to his involvement in the ill-fated campaign against Ramoth-gilead. Despite the warnings of the prophet Micaiah, who foretold disaster, Jehoshaphat joined Ahab in battle. Ahab was killed, and Jehoshaphat narrowly escaped with his life (1 Kings 22:29-33). Upon his return to Jerusalem, Jehoshaphat was rebuked by the prophet Jehu for helping the wicked and loving those who hate the Lord (2 Chronicles 19:2).

Judicial Reforms and Spiritual Leadership

In response to the rebuke, Jehoshaphat implemented further reforms, appointing judges throughout the land and charging them to judge with the fear of the Lord, with integrity and without partiality (2 Chronicles 19:5-7). He also established a judicial system in Jerusalem, appointing Levites, priests, and family heads to administer the law of the Lord and settle disputes (2 Chronicles 19:8-11).

The Moabite and Ammonite Invasion

Jehoshaphat's faith was tested when a vast army from Moab and Ammon came against Judah. In response, he proclaimed a fast and gathered the people at the temple to seek the Lord's help. Jehoshaphat's prayer, recorded in 2 Chronicles 20:5-12, is a profound expression of trust in God's sovereignty and power. The Lord answered through the prophet Jahaziel, assuring victory without the need for battle. As the people sang and praised, the Lord set ambushes against the invaders, leading to their defeat (2 Chronicles 20:15-23).

Later Years and Legacy

Jehoshaphat's later years were marked by continued efforts to strengthen Judah spiritually and militarily. However, his alliance with Ahaziah, king of Israel, in a maritime venture was unsuccessful and condemned by the prophet Eliezer (2 Chronicles 20:35-37). Jehoshaphat died and was buried in the city of David, succeeded by his son Jehoram (1 Kings 22:50).

Jehoshaphat's reign is remembered for his dedication to the Lord, his reforms, and his efforts to lead Judah in righteousness. His account serves as a testament to the blessings of seeking God and the dangers of compromising alliances.
