2 Kings 3 is a chapter that focuses on the reign of Jehoram, the son of Ahab and Jezebel. This chapter begins with the death of Jehoshaphat, the king of Judah, and the ascension of Jehoram to the throne of Judah. Jehoram then makes an alliance with the king of Israel, Jehoram's brother, and the king of Edom to fight against the Moabites. The three kings march against the Moabites, but they are unsuccessful in their efforts.
The chapter then shifts to the prophet Elisha, who is sent by God to help the three kings in their battle against the Moabites. Elisha instructs the kings to dig ditches in the desert, and when they do, the water miraculously appears and allows the kings to defeat the Moabites. After the victory, the kings return to their respective kingdoms.
This chapter is a reminder of the power of God and His ability to intervene in the affairs of men. It also serves as a reminder of the importance of faith and obedience to God's commands. The kings of Israel, Judah, and Edom were willing to put their trust in God and follow His instructions, and in doing so, they were able to achieve victory. This chapter is a reminder that when we put our trust in God, He will provide us with the strength and guidance we need to succeed.
