17 Son of man, I have made you a watchman for the children of Israel: so give ear to the word of my mouth, and give them word from me of their danger. 18 When I say to the evil-doer, Death will certainly be your fate; and you give him no word of it and say nothing to make clear to the evil-doer the danger of his evil way, so that he may be safe; that same evil man will come to death in his evil-doing; but I will make you responsible for his blood. 19 But if you give the evil-doer word of his danger, and he is not turned from his sin or from his evil way, death will overtake him in his evil-doing; but your life will be safe. 20 Again, when an upright man, turning away from his righteousness, does evil, and I put a cause of falling in his way, death will overtake him: because you have given him no word of his danger, death will overtake him in his evil-doing, and there will be no memory of the upright acts which he has done; but I will make you responsible for his blood. 21 But if you say to the upright man that he is not to do evil, he will certainly keep his life because he took note of your word; and your life will be safe.

Commentary on Ezekiel 3:12-21
(Read Ezekiel 3:12-21)
This mission made the holy angels rejoice. All this was to convince Ezekiel, that the God who sent him had power to bear him out in his work. He was overwhelmed with grief for the sins and miseries of his people, and overpowered by the glory of the vision he had seen. And however retirement, meditation, and communion with God may be sweet, the servant of the Lord must prepare to serve his generation. The Lord told the prophet he had appointed him a watchman to the house of Israel. If we warn the wicked, we are not chargeable with their ruin. Though such passages refer to the national covenant made with Israel, they are equally to be applied to the final state of all men under every dispensation. We are not only to encourage and comfort those who appear to be righteous, but they are to be warned, for many have grown high-minded and secure, have fallen, and even died in their sins. Surely then the hearers of the gospel should desire warnings, and even reproofs.
