Then he wrote a letter the second time to them, saying, If ye [be] mine, and [if] ye will hearken unto my voice, take ye the heads of the men your master’s sons, and come to me to Jezreel by to morrow this time. Now the king’s sons, [being] seventy persons, [were] with the great men of the city, which brought them up.
