2 Corinthians 4:4 identifies the god of this world (Satan) as the one who blinds unbelievers, specifying the agent behind the veil.

2 Corinthians 4:3 states that the gospel is veiled to the perishing, directly paralleling the parables' hiding function for those outside.

Isaiah 42:18-20 describes Israel as blind and deaf despite seeing and hearing — the same spiritual blindness Jesus notes in Matthew 13:13.

John 3:20 adds that evildoers hate the light and avoid it to prevent exposure, further detailing the willful blindness.

Jeremiah 5:21 uses the same 'eyes but see not' language to describe Israel's stubborn unbelief, showing this is a longstanding prophetic indictment.

Ezekiel 12:2 similarly describes rebellious Israel with eyes that see not and ears that hear not, reinforcing the OT prophetic pattern.

John 3:19 explains the root cause: people love darkness rather than light because their deeds are evil, giving the moral reason for their blindness.

Mark 8:18 repeats the exact 'eyes having do you not see' question, echoing Jesus' earlier diagnosis of spiritual dullness.

Deuteronomy 29:4 says God gave Israel no heart to understand, eyes to see, or ears to hear — identical to the condition in Matthew 13:13.

Psalm 78:2 introduces teaching in parables and dark sayings — Jesus' method in Matthew 13:13 fulfills this prophetic pattern.
