Ezekiel 3:5-6
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!
Ezekiel 20:49
20:49 Then I said, “O sovereign Lord! They are saying of me, ‘Does he not simply speak in eloquent figures of speech?’”
