Ezekiel 2:5

וַיֹּאמֶר אֵלַי בֶּן־אָדָם שׁוֹלֵחַ אֲנִי אֽוֹתְךָ אֶל־בְּנֵי יִשְׂרָאֵל אֶל־גּוֹיִם הַמּוֹרְדִים אֲשֶׁר מָרְדוּ־בִי הֵמָּה וַאֲבוֹתָם פָּשְׁעוּ בִי עַד־עֶצֶם הַיּוֹם הַזֶּֽה

And He said unto me: ‘Son of man, I send thee to the children of Israel, to rebellious nations, that have rebelled against Me; they and their fathers have transgressed against Me, even unto this very day;

וְהַבָּנִים קְשֵׁי פָנִים וְחִזְקֵי־לֵב אֲנִי שׁוֹלֵחַ אוֹתְךָ אֲלֵיהֶם וְאָמַרְתָּ אֲלֵיהֶם כֹּה אָמַר אֲדֹנָי יְהֹוִֽה

and the children are brazen-faced and stiff-hearted, I do send thee unto them; and thou shalt say unto them: Thus saith the Lord GOD.

וְאַתָּה בֶן־אָדָם אַל־תִּירָא מֵהֶם וּמִדִּבְרֵיהֶם אַל־תִּירָא כִּי סָרָבִים וְסַלּוֹנִים אוֹתָךְ וְאֶל־עַקְרַבִּים אַתָּה יוֹשֵׁב מִדִּבְרֵיהֶם אַל־תִּירָא וּמִפְּנֵיהֶם אַל־תֵּחָת כִּי בֵּית מְרִי הֵֽמָּה

And thou, son of man, be not afraid of them, neither be afraid of their words, though defiers and despisers be with thee, and thou dost dwell among scorpions; be not afraid of their words, nor be dismayed at their looks, for they are a rebellious house.

וְדִבַּרְתָּ אֶת־דְּבָרַי אֲלֵיהֶם אִֽם־יִשְׁמְעוּ וְאִם־יֶחְדָּלוּ כִּי מְרִי הֵֽמָּה

And thou shalt speak My words unto them, whether they will hear, or whether they will forbear; for they are most rebellious.
