Ezekiel 33:2-4

New Revised Standard Version Catholic Edition

² O Mortal, speak to your people and say to them, If I bring the sword upon a land, and the people of the land take one of their number as their sentinel; ³ and if the sentinel sees the sword coming upon the land and blows the trumpet and warns the people; ⁴ then if any who hear the sound of the trumpet do not take warning, and the sword comes and takes them away, their blood shall be upon their own heads.
