There are many strange details in 2nd Kings 3, but the backstory is a rebellion of the ancient kingdom of Moab that roped in the northern and southern kingdoms of Israel and Edom to the southeast.
This chapter helps illustrate apostle Paul’s teaching that the “wages of sin is death” (Rom. 6:23). In this case, the wages of Moab’s rebellion was death.
Did you realize that the ministry of the apostle Peter was prophesied in Scripture? Just as Eliyahu (Elijah) has a New Testament equivalent in Yokhanan (John the Baptist), Elisha also has a New Testament equivalent: Peter.
2nd Kings 1 is all about rebellion, the rebellion of Moab against Israelite rule after Ahab’s death as well as Ahab’s son’s rebellion against God and the consequences of that rebellion that flowed through Israel’s army. Eliyahu showed both Ahaziah and his army that God (and God’s servants) deserved respect.
In 1st Kings 22, we read about the final events that lead up to Ahab’s death. For those of us who are trying to walk a righteous life, the mistake and foibles of the unrighteous can still provide us powerful lessons, including the danger of making promises in haste and only listening to part of God’s instruction rather than all of it, but probably the most important lesson from this final chapter of Ahab’s life is that God does not need 400 voices to teach you His truth. He only needs one.
It had been 70 years since Israel had any exposure to the temple in Yerushalayim (Jerusalem) and to God. Eliyahu (Elijah) is starting from scratch with them. Eliyahu’s story is God’s message to Israel. It’s all tied together. Eliyahu’s interactions with Ahab and Yezebel (Jezebel) dominate the story but the purpose of these interactions were to teach the people of Israel about God.
We can see here how Israel has progressed in their knowledge of God and His law since Eliyahu started his ministry.
Whether the children of the Northern Tribes had forgotten God on accident or on purpose, the result has been the same: apostasy. Eliyahu (Elijah) had an uphill battle trying to reintroduce God to the children of Israel.
Ahab had a soft-spot for evil, both physical (Ben-Hadad) and spiritual (Yezebel). But as we read later on, Ahab started to learn that God is above him.
Just as God didn’t let the prophet Eliyahu (Elijah) quit from the mission, God doesn’t want us to become discouraged and quit our tasks.
