Ezekiel 33:6-8

New Revised Standard Version Catholic Edition

⁶ But if the sentinel sees the sword coming and does not blow the trumpet, so that the people are not warned, and the sword comes and takes any of them, they are taken away in their iniquity, but their blood I will require at the sentinel’s hand.

⁷ So you, mortal, I have made a sentinel for the house of Israel; whenever you hear a word from my mouth, you shall give them warning from me. ⁸ If I say to the wicked, “O wicked ones, you shall surely die,” and you do not speak to warn the wicked to turn from their ways, the wicked shall die in their iniquity, but their blood I will require at your hand.
