2 Kings 10:10

6Then 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.

7And it came to pass, when the letter came to them, that they took the king’s sons, and slew seventy persons, and put their heads in baskets, and sent him them to Jezreel.

8And there came a messenger, and told him, saying, They have brought the heads of the king’s sons. And he said, Lay ye them in two heaps at the entering in of the gate until the morning.

9And it came to pass in the morning, that he went out, and stood, and said to all the people, Ye be righteous: behold, I conspired against my master, and slew him: but who slew all these?

10Know now that there shall fall unto the earth nothing of the word of the Lord, which the Lord spake concerning the house of Ahab: for the Lord hath done that which he spake by his servant Elijah.

11So Jehu slew all that remained of the house of Ahab in Jezreel, and all his great men, and his kinsfolks, and his priests, until he left him none remaining.

12And he arose and departed, and came to Samaria. And as he was at the shearing house in the way,

13Jehu met with the brethren of Ahaziah king of Judah, and said, Who are ye? And they answered, We are the brethren of Ahaziah; and we go down to salute the children of the king and the children of the queen.

14And he said, Take them alive. And they took them alive, and slew them at the pit of the shearing house, even two and forty men; neither left he any of them.
