2 Kings 3:24-27
24 But when the Moabites came to the camp of Israel, the Israelites rose up and fought them until they fled. And the Israelites invaded the land and slaughtered the Moabites. 25 They destroyed the towns, and each man threw a stone on every good field until it was covered. They stopped up all the springs and cut down every good tree. Only Kir Hareseth was left with its stones in place, but men armed with slings surrounded it and attacked it.
26 When the king of Moab saw that the battle had gone against him, he took with him seven hundred swordsmen to break through to the king of Edom, but they failed. 27 Then he took his firstborn son, who was to succeed him as king, and offered him as a sacrifice on the city wall. The fury against Israel was great; they withdrew and returned to their own land.
If I am understanding the text correctly, King of Moab has sacrificed the first son causing fury against Israel, and the army of Israel withdraws. My question is who is furious against Israel? The people? God? Or someone else? How does this cause them to withdraw?
