Ezekiel 3:5-7

New Revised Standard Version, Anglicised

⁵ For you are not 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 sent you to them, they would listen to you. ⁷ But the house of Israel will not listen to you, for they are not willing to listen to me; because all the house of Israel have a hard forehead and a stubborn heart.
