Ezekiel 33:3-5

EJ2000(i) 3 and he should see the sword coming upon the land, if he should blow the shofar, and warn the people, 4 then whoever hears the sound of the shofar and does not take warning; and the coming of the sword should take him away, his blood shall be upon his own head. 5 He heard the sound of the shofar and did not take warning; his blood shall be upon himself. But he that takes warning shall deliver his soul.
