17 "Son of man, I've made you a watchman for the family of Israel. Whenever you hear me say something, warn them for me. 18 If I say to the wicked, 'You are going to die,' and you don't sound the alarm warning them that it's a matter of life or death, they will die and it will be your fault. I'll hold you responsible. 19 But if you warn the wicked and they keep right on sinning anyway, they'll most certainly die for their sin, but you won't die. You'll have saved your life. 20 "And if the righteous turn back from living righteously and take up with evil when I step in and put them in a hard place, they'll die. If you haven't warned them, they'll die because of their sins, and none of the right things they've done will count for anything - and I'll hold you responsible. 21 But if you warn these righteous people not to sin and they listen to you, they'll live because they took the warning - and again, you'll have saved your life."

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.
