Ezekiel 3:4-7

4He said to me, “Son of man, go to the house of Israel and speak my words to them.

5For you are not being sent to a people of unintelligible speech and difficult language, but to the house of Israel –

6not to many peoples of unintelligible speech and difficult language, whose words you cannot understand – surely if I had sent you to them, they would listen to you!

7But the house of Israel is unwilling to listen to you, because they are not willing to listen to me, for the whole house of Israel is hard-headed and hard-hearted.
