Ezekiel 3:5-7

Young's Literal Translation

⁵ For, not unto a people deep of lip and heavy of tongue [art] thou sent -- unto the house of Israel;

⁶ not unto many peoples, deep of lip and heavy of tongue, whose words thou dost not understand. If I had not sent thee unto them -- they, they do hearken unto thee,

⁷ but the house of Israel are not willing to hearken unto thee, for they are not willing to hearken unto Me, for all the house of Israel are brazen-faced and strong-hearted.
