Acts 23:14-15

And they came to the chief priests and elders Who were of the sect of the Sadducees, and Paul's greatest enemies, telling them what they had done; and desiring them to ask the chief captain to bring Paul down to the council on the morrow, as if they wished to inquire something more perfectly concerning him, and we, (said they,) or ever he come near, are ready to kill him And we will manage the attack in such a manner, that you shall not appear at all concerned in it; nor have any alarm about the matter, till you hear that he is actually dead. Josephus mentions a case not much unlike this, of some that bound themselves with an oath to kill Herod; in which they gloried as a laudable intention, because he had violated the ancient customs of their nation. It is no wonder, therefore, that these Jews should make no scruple of acquainting the chief priests and elders with their conspiracy against the life of Paul; who, indeed, were so far from blaming them for it, that not long after they renewed the same design themselves. See Acts 25:2.
