ACT 23:21

21 Do not do what they ask you [(sg)] to do, because there are more than 40 [Jewish] men who will be hiding and waiting [to attack Paul when he passes by on the way to the Council]. They even promised/vowed to God that they will not eat or drink anything until they have killed Paul. They are ready [to do it], and right now they are waiting for you [(sg)] to agree [to do what they are asking you to do].”
