Ezekiel 3:7

4 And he said to me, Son of man, go now to the children of Israel, and say my words to them.

5 For you are not sent to a people whose talk is strange and whose language is hard, but to the children of Israel;

6 Not to a number of peoples whose talk is strange and whose language is hard and whose words are not clear to you. Truly, if I sent you to them they would give ear to you.

7 But the children of Israel will not give ear to you; for they have no mind to give ear to me: for all the children of Israel have a hard brow and a stiff heart.

8 See, I have made your face hard against their faces, and your brow hard against their brows.

9 Like a diamond harder than rock I have made your brow: have no fear of them and do not be overcome by their looks, for they are an uncontrolled people.

10 Then he said to me, Son of man, take into your heart all my words which I am about to say to you, and let your ears be open to them.
