Yechezkel 33:2-4

Orthodox Jewish Bible

² Ben Adam, speak to the Bnei Amecha, and say unto them, When I bring the cherev upon eretz, if the Am HaAretz take ish echad (one man) within their midst, and appoint him for their tzofeh (watchman, sentinel),

³ If when he seeth the cherev come upon HaAretz, he blow the shofar, and warn HaAm;

⁴ Then whosoever heareth the sound of the shofar, and taketh not warning; if the cherev come, and take him away, his dahm shall be upon his own rosh.
