Acts 23:20-21

20And he said, The Jews have agreed together to make a request to thee, that thou mayest bring Paul down to-morrow into the council, as about to inquire something more precise concerning him.

21Do not thou then be persuaded by them, for there lie in wait for him of them more than forty men, who have put themselves under a curse neither to eat nor drink till they kill him; and now they are ready waiting the promise from thee.
