17 Mortal, I have made you a sentinel for the house of Israel; whenever you hear a word from my mouth, you shall give them warning from me. 18 If I say to the wicked, "You shall surely die," and you give them no warning, or speak to warn the wicked from their wicked way, in order to save their life, those wicked persons shall die for their iniquity; but their blood I will require at your hand. 19 But if you warn the wicked, and they do not turn from their wickedness, or from their wicked way, they shall die for their iniquity; but you will have saved your life. 20 Again, if the righteous turn from their righteousness and commit iniquity, and I lay a stumbling block before them, they shall die; because you have not warned them, they shall die for their sin, and their righteous deeds that they have done shall not be remembered; but their blood I will require at your hand. 21 If, however, you warn the righteous not to sin, and they do not sin, they shall surely live, because they took warning; and you will have saved your life.
Matthew Henry's Commentary on Ezekiel 3:17-21
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.
