And Jehu drew a bow with his full strength, and smote Jehoram between his arms, and the arrow went out at his heart, and he sunk down in his chariot. Drew a bow with his full strength - The marginal reading is correct: He filled his hand with a bow. That is, "He immediately took up his bow, set his arrow, and let fly." This is the only meaning of the passage.
Between his arms - That is, between his shoulders; for he was now turned, and was flying from Jehu.
