2 Kings 10:6 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. (KJV Authorized version 1611)
