Ezekiel 3:4-7  NAS

Then He said to me, "Son of man, go to the house of Israel and speak My words to them.  For you are not being sent to a people of unintelligible speech or difficult language, but to the house of Israel, nor to many peoples of unintelligible speech or difficult language, whose words you cannot understand.  But I have sent you to them who should listen to you; yet the house of Israel will not be willing to listen to you, since they are not willing to listen to me.
