Which rivers of Damascus did Naaman say were better than all the waters of Israel?

Answer: Abanah and Pharpar

Angry at Elisha's instructions, Naaman asked, "Are not the Abanah and Pharpar, the rivers of Damascus, better?"

“Are not the Abanah and Pharpar, the rivers of Damascus, better than all the waters of Israel? Could I not have washed in them and been cleansed?” So he turned and went away in a rage.”— 2 Kings 5:12 (BSB)
