In Ezekiel 2:6, God first commands 'do not be afraid' of the rebellious people — here He makes Ezekiel's face hard as diamond to enable that fearlessness.

Isaiah 50:7 echoes the same 'set my face like flint' imagery — divine resolve to face opposition without shame.

Jeremiah 1:18 reinforces the same commissioning pattern: God makes the prophet unconquerable like fortifications against enemies.

Jeremiah 15:20 repeats the ‘bronze wall’ promise — another prophet hardened by God to withstand relentless opposition.

Jeremiah 6:27 casts the prophet as a metal assayer — a different metaphor but the same divine appointment to test and confront.
