Ezekiel 3:4-8
4 He then said to me: “Son of man, go now to the house of Israel and speak my words to them.
5 You are not being sent to a people of obscure speech and difficult language, but to the house of Israel—
6 not to many peoples of obscure speech and difficult language, whose words you cannot understand. Surely if I had sent you to them, they would have listened to you.
7 But the house of Israel is not willing to listen to you because they are not willing to listen to me, for the whole house of Israel is hardened and obstinate.
8 But I will make you as unyielding and hardened as they are.
