Ezekiel 33:4 presents the opposite case: if the watchman fails to warn, the blood is on his hands — contrasting with the warned person's self-responsibility here.

Ezekiel 3:19 provides the earlier version of this same watchman principle: the warned wicked dies in his iniquity, but the watchman is cleared.

Ezekiel 18:27 states that the wicked who turns saves his life — directly parallel to the condition of heeding warning in this verse.

Exodus 9:19-21 shows Egyptians who heeded the warning about the hail were saved, while those who ignored perished—a direct parallel to the trumpet warning and personal responsibility.

In 2 Kings 6:10, the king heeds the prophet's warning about an ambush and is saved—illustrating the blessing of responding to a watchman's alert.

In Acts 2:37-41, the crowd's response to Peter's warning — repentance and baptism — parallels heeding the trumpet call to save one's life.

Hebrews 2:1-3 warns that ignoring the message of salvation brings just punishment—matching the principle that those who hear but ignore the trumpet are accountable.

Hebrews 11:7 shows Noah heeding God's warning to build the ark, contrasting with those who ignore the trumpet — same principle of obedient faith saving life.

Joshua 2:19 uses identical language: 'his blood shall be on his own head' for Rahab's household, tying personal responsibility for heeding protection.

2 Samuel 1:16 echoes 'your blood be on your own head' as David judges the Amalekite — same phrase for bearing consequences of one's own actions.

Proverbs 19:16 links keeping commandments to preserving life — a general wisdom parallel to the specific warning-response dynamic here.
