Acts 23:12-15

And when it was day, the Jews banded together, and bound themselves under a curse, saying that they would neither eat nor drink till they had killed Paul. And they were more than forty that made this conspiracy. And they came to the chief priests and the elders, and said, We have bound ourselves under a great curse, to taste nothing until we have killed Paul. Now therefore do ye with the council signify to the chief captain that he bring him down unto you, as though ye would judge of his case more exactly: and we, before he comes near, are ready to slay him.
