Isaiah 48:4

48:4 I did this because I know how stubborn you are.

Your neck muscles are like iron

and your forehead like bronze.

Jeremiah 5:3

5:3 Lord, I know you look for faithfulness.

But even when you punish these people, they feel no remorse.

Even when you nearly destroy them, they refuse to be corrected.

They have become as hardheaded as a rock.

They refuse to change their ways.

Jeremiah 6:29-30

6:29 The fiery bellows of judgment burn fiercely.

But there is too much dross to be removed.

The process of refining them has proved useless.

The wicked have not been purged.

6:30 They are regarded as ‘rejected silver’

because the Lord rejects them.”

Zechariah 7:11-12

7:11 “But they refused to pay attention, turning away stubbornly and stopping their ears so they could not hear. 7:12 Indeed, they made their heart as hard as diamond, so that they could not obey the Torah and the other words the Lord who rules over all had sent by his Spirit through the former prophets. Therefore, the Lord who rules over all had poured out great wrath.
