The book of 2nd Kings gives us a glimpse of who Jesus is in the Old Testament (O.T).
2nd Kings 5 records a fascinating story about a mighty man named Naaman, who despite his mightiness was a leper in his skin and an unnamed little maid from Israel brings about salvation to his household, by pointing Naaman to the prophet of God, Elisha. Now we must be careful to note that it was not the prophet that healed Naaman, but it was God who was with the prophet as expressed by the little maid’s words (2 Kings 5:3). The prophet said, Wash and be clean. (2 Kings 5:13). Naaman skin was restored like a child (a new born child – a new creation) , and Naaman’s proclamation was not about the prophet, but about the God of the prophet when he says. Now I know that there is no God in ALL the earth, but in Israel (2 Kings 5:15)
Move forward a few centuries -
You see a leper coming to Jesus, beseeching Him and kneeling down to him and saying if thou wilt, thou canst make me clean (Mark 1:40) . Jesus moved with compassion, put forth his hand and touched him and said, I will be thou clean. On the cross, Jesus moved with compassion, stretched out his hand and touched the hearts of all who heard Him then and hear Him now, (not I will but) I have borne your leprosy (sin), be thou clean (Holy). The blood of Jesus washes us of all unrighteousness and makes us clean. (1 John 1:7).
In 2nd Kings, Behold, Jesus the healer of our leprous state.
