2 Kings 10:7, 14

When the letter came to them, they took the king’s sons and slaughtered them, seventy persons, and put their heads in baskets, and sent them to Jehu at Jezreel.

Then Jehu said, “Take them alive.” So they took them alive and [later] slaughtered them at the well by the place of the sand heaps, forty-two men; he left none of them [alive].
