Ezekiel 3:27

But when I speak with thee, I will open thy mouth, in revealing the judgment of God upon his countrymen, and thou shalt say unto them, Thus saith the Lord God, He that heareth, let him hear, and he that forbeareth, let him forbear; for they are a rebellious house, and therefore would have only themselves to blame for the calamity which would surely strike them. Every pastor, as the Lord's watchman in the midst of his congregation, has a tremendous responsibility resting upon him, both in calling sinners to repentance and in warning the believers against the ways of unrighteousness. One negligent in this duty is a murderer of souls.
