So he who was over the palace, and he who was over the city, together with the elders and the guardians, sent to Jehu, saying, "We are your servants, and we will do all that you bid us. We will not make any one king; do whatever is good in your eyes."
Then he wrote to them a second letter, saying, "If you are on my side, and if you are ready to obey me, take the heads of your master's sons, and come to me at Jezreel tomorrow at this time." Now the king's sons, seventy persons, were with the great men of the city, who were bringing them up.
And when the letter came to them, they took the king's sons, and slew them, seventy persons, and put their heads in baskets, and sent them to him at Jezreel.
When the messenger came and told him, "They have brought the heads of the king's sons," he said, "Lay them in two heaps at the entrance of the gate until the morning."
Then in the morning, when he went out, he stood, and said to all the people, "You are innocent. It was I who conspired against my master, and slew him; but who struck down all these?
Know then that there shall fall to the earth nothing of the word of the LORD, which the LORD spoke concerning the house of Ahab; for the LORD has done what he said by his servant Eli'jah."
So Jehu slew all that remained of the house of Ahab in Jezreel, all his great men, and his familiar friends, and his priests, until he left him none remaining.
Then he set out and went to Sama'ria. On the way, when he was at Beth-eked of the Shepherds,
Jehu met the kinsmen of Ahazi'ah king of Judah, and he said, "Who are you?" And they answered, "We are the kinsmen of Ahazi'ah, and we came down to visit the royal princes and the sons of the queen mother."
He said, "Take them alive." And they took them alive, and slew them at the pit of Beth-eked, forty-two persons, and he spared none of them.
And when he departed from there, he met Jehon'adab the son of Rechab coming to meet him; and he greeted him, and said to him, "Is your heart true to my heart as mine is to yours?" And Jehon'adab answered, "It is." Jehu said, "If it is, give me your hand." So he gave him his hand. And Jehu took him up with him into the chariot.
