Ezekiel 33:1-6

God establishes the watchman principle: when the watchman sees the sword coming and blows the trumpet, the people are warned — if they fail to heed, their blood is on their own heads. But if the watchman sees the enemy and does NOT blow the trumpet, the people perish — and "his blood I will require from the watchman's hand" (v.6). This principle illuminates Adam's sin: he was placed as watchman over the garden (Gen 2:15, shamar), he saw the enemy (the serpent), he heard the deception being spoken to his wife, he knew it was false (he was not deceived, 1 Tim 2:14), and he said nothing. The watchman's guilt is not in the enemy's attack but in his silence. Adam's sin was the silence of the watchman who refused to warn.
