Albert Barnes Commentary 2 Kings 9:24

"And Jehu drew his bow with his full strength, and smote Joram between his arms; and the arrow went out at his heart, and he sunk down in his chariot." — 2 Kings 9:24 (ASV)

Jehu drew a bow ... - literally, as in the margin, that is, “Jehu took a bow in his hand.” The arrow struck Jehoram’s back, between his two shoulders, as he fled.
