Charles Spurgeon Commentary Zechariah 7:11-12

"But they refused to hearken, and pulled away the shoulder, and stopped their ears, that they might not hear. Yea, they made their hearts as an adamant stone, lest they should hear the law, and the words which Jehovah of hosts had sent by his Spirit by the former prophets: therefore there came great wrath from Jehovah of hosts." — Zechariah 7:11-12 (ASV)

And rightly so. When God requires what is so just and so commendable, and people will not yield to it, and will not even hear about it, they deserve for God to grow wrathful with them.
