It was Ahab’s house that was asking for peace, but they were asking for physical peace, not God’s peace. God does not like the world’s definition of peace, which is, “Leave me alone! I enjoy my miserable life.” When someone is at war with God and they are about to see God’s sword coming down on them, they will ask for “peace.” But in this account, they were lying.
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.
The clash on Mt. Carmel between Eliyahu (Elijah) and the priests of Ba’al was part of bigger clash between a rebellious king of the northern kingdom, Ahab, and his foreign queen, Yezebel (Jezebel), and her false gods.
Among the prophets of the north who Eliyahu saves from the purge of YHWH’s servants was ObidaYah (Obidaiah), possibly the same one who wrote a short book of the Bible.
