Ezekiel 3:4-9

4He then said to me: “Son of man, go now to the people of Israel and speak my words to them. 5You are not being sent to a people of obscure speech and strange language, but to the people of Israel— 6not to many peoples of obscure speech and strange language, whose words you cannot understand. Surely if I had sent you to them, they would have listened to you. 7But the people of Israel are not willing to listen to you because they are not willing to listen to me, for all the Israelites are hardened and obstinate. 8But I will make you as unyielding and hardened as they are. 9I will make your forehead like the hardest stone, harder than flint. Do not be afraid of them or terrified by them, though they are a rebellious people.”
