And he said to me, “Son of man, stand on your feet, and I will speak with you.”  And as he spoke to me, the Spirit entered into me and set me on my feet, and I heard him speaking to me.  And he said to me, “Son of man, I send you to the people of Israel, to nations of rebels, who have rebelled against me. They and their fathers have transgressed against me to this very day.  The descendants also are impudent and stubborn: I send you to them, and you shall say to them, ‘Thus says the Lord GOD.’  And whether they hear or refuse to hear (for they are a rebellious house) they will know that a prophet has been among them.
(Ezekiel 2:1-5 ESV)
