2 Kings 5:14-17

14So he went down and dipped in the Jordan seven times, as the prophet had instructed. His skin became as smooth as a young child’s and he was healed.

15He and his entire entourage returned to the prophet. Naaman came and stood before him. He said, “For sure I know that there is no God in all the earth except in Israel! Now, please accept a gift from your servant.”

16But Elisha replied, “As certainly as the Lord lives (whom I serve), I will take nothing from you.” Naaman insisted that he take it, but he refused.

17Naaman said, “If not, then please give your servant a load of dirt, enough for a pair of mules to carry, for your servant will never again offer a burnt offering or sacrifice to a god other than the Lord.
