Maid of Naaman's wife
A captive Israelite girl became the maid of Naaman's wife. Naaman suffered from leprosy. The maid knew of the prophet Elisha and told Naaman's wife about him.
I wish that my master [Naaman] were with the prophet who is in Samaria! Then he would heal him of his leprosy.— 2 Kings 5:3 (AMP)
Naaman then told the King of Aram (Syria) about what the maid said:
The girl who is from the land of Israel said such and such. (2 Kings 5:4 (AMP)). The King then allowed Naaman to go to Israel and provided him with a letter that asked King Jehoram of Israel to heal Naaman of his leprosy.
Naaman brought ten talents of silver and six thousand shekels of gold with me on the journey into Israel.
Naaman presented the letter to King Jehoram of Israel, and Jehoram tore his clothes, said that he could not perform the works that only God can do, and suggested that the request and his inability to carry it out might be an attempt to obtain a casus belli for war.
Elisha learned about the incident and asked the King to ask Naaman to him. Naaman went to Elisha, and Elisha commanded him to wash in the river Jordan seven times. Naaman did not believe that washing in the river alone could cure him and expressed displeasure. As Naaman was leaving, his servants convinced him to do as the prophet commanded. Naaman did as Elisha had instructed, washing himself in the Jordon seven times, and was cured.
Naaman returned to Elisha, acknowledged the God of Israel as the one true God, and attempted to give a gift to Elisha.
Behold, I know that there is no God in all the earth, except in Israel; so now accept a blessing and gift from your servant.— 2 Kings 15 (AMP)
Elisha refused the gift. Naaman then asked for dirt from Israel to take back to Aram (Syria) and for God's pardon when his duties to the King of Aram interfere with his newfound faith in the God of Israel.
If not, then please, let your servant be given a load of earth for a team of mules; for [from this day on] your servant will no longer offer a burnt offering nor a sacrifice to other gods, but only to the Lord, [the God of Israel]. In this matter may the Lord pardon your servant: when my master [the king] goes into the house of [his god] Rimmon to worship there, and he leans on my hand and I bow in the house of Rimmon, when I bow down in the house of Rimmon, may the Lord pardon your servant in this matter [of attending the king when he worships].— 2 Kings 5:17–5:18 (AMP)
Elisha allowed him to take the dirt, telling him,
Go in peace (2 Kings 5:19 (AMP)).
