Answer: Elisha
Explanation:
Elisha was a great prophet and the successor to Elijah. He was Israel's most revered prophet in the time of Naaman who was the Commander of the forces of the Kingdom of Aram.
Naaman was a leper who had married a young girl from Israel who his forces had captured. She convinced him to go see Prophet Elisha who told him to go dip himself 7 times in the River Jordan which he did after some initial reluctance.
After the 7th dip, his skin was healed by Yahweh and demonstrated Yahweh’s supremacy and grace to all people, even those outside the covenant community of Israel.
