John Gill Commentary 2 Chronicles 22:6

"And he returned to be healed in Jezreel of the wounds which they had given him at Ramah, when he fought against Hazael king of Syria. And Azariah the son of Jehoram king of Judah went down to see Jehoram the son of Ahab in Jezreel, because he was sick." — 2 Chronicles 22:6 (ASV)
