Ezekiel 3:20-21

20Again, when a righteous man turns from his righteousness (right standing with God) and sins, and I place an obstacle before him, he will die; since you have not warned him, he will die in his sin, and the righteous deeds which he has done will not be remembered; but you will be responsible for his blood.

21However, if you have warned the righteous man not to sin and he does not sin, he will surely live because he took warning; also you have freed yourself [from responsibility].”
