Entonces Joram dijo: Unce. Y uncido que fué su carro, salió Joram rey de Israel, y Ochôzías rey de Judá, cada uno en su carro, y salieron á encontrar á Jehú, al cual hallaron en la heredad de Naboth de Jezreel.
Rashi
the blood of Jezreel To be understood according to its Aramaic translation: the blood of the house of Ahab, whom Jehu slew in Jezreel because they worshipped Baal, and he and his sons went afterwards and worshipped pagan deities; therefore, I account for them the blood of the house of Ahab as innocent blood.
