Ezekiel 3:4-6

3:4 He said to me, “Son of man, go to the house of Israel and speak my words to them. 3:5 For you are not being sent to a people of unintelligible speech and difficult language, but to the house of Israel – 3:6 not 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!
