The verse highlights a chilling deliberate choice: their hearts weren't just hard, they were made hard, like diamond, specifically to prevent them from hearing God's Word. This wasn't an accidental hardness, but a conscious, willful resistance, showing that deep-seated disobedience can be a chosen defense against divine truth.
The people of Jerusalem had asked Zechariah if they should continue observing their solemn fasts. In response, the prophet recounts how their ancestors stubbornly refused to listen to God's messengers, hardening their hearts like diamond so they wouldn't hear the Law and the prophets' warnings. Because of this deep-seated rebellion, God's great anger had fallen upon them, a consequence the current generation should heed.
Ever felt like a door slammed shut, refusing to let anything in? That's what Zechariah describes for the hearts of his people.
The people had, by deliberate choice, made their hearts like 'adamant'—an incredibly hard stone, perhaps diamond. This wasn't a passive state but an active hardening. They made their hearts this way.
A Chosen Refusal
This 'adamant heart' meant that God’s words, sent by His Spirit, could not penetrate or engrave themselves upon their minds and wills. They were impenetrable.
When God speaks, especially through His Spirit, what happens when we refuse to listen? Zechariah gives a stark answer.
The intentional hardening of their hearts had a direct and severe consequence: 'therefore came a great wrath from the LORD of hosts.'
