Ezekiel 3:8

“Because I know that you are stiff, And your neck is an iron sinew And your forehead bronze,

Even now Lord Yahweh helps Me, Therefore, I am not dishonored; Therefore, I have set My face like flint, And I know that I will not be ashamed.

O Yahweh, do not Your eyes look for faithfulness? You have struck them, But they did not weaken; You have consumed them, But they refused to receive discipline. They have made their faces stronger than rock; They have refused to repent.

“And they made their hearts diamond-hard so that they could not hear the law and the words which Yahweh of hosts had sent by His Spirit by the hand of the former prophets; therefore great wrath came from Yahweh of hosts.
