“And when the king of Israel read the letter, he tore his clothes …” (v7). When the king of Israel heard that Syria’s king expected him to cure the general, Naaman, of leprosy, he responded in anger and disbelief. In contrast, the young Israelite servant girl who had been kidnapped and taken to Syria to serve Naaman’s wife was totally convinced that God could heal the man. Her faith convinced the Syrian general to trust in Israel’s God and wash in the Jordan, though the king himself doubted.
“Wash and be clean” (v13). God responds to anyone – servant, child, pagan general – who calls on Him in faith and accepts His Word as true.
