Such was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell on my face, and I heard the voice of one speaking.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." Then the Spirit lifted me up, and I heard behind me the voice  of a great earthquake: "Blessed be the glory of the LORD from its place!" It was the sound of the wings of the living creatures as they touched one another, and the sound of the wheels beside them, and the sound of a great earthquake. The Spirit lifted me up and took me away, and I went in bitterness in the heat of my spirit, the hand of the LORD being strong upon me.

This might be kind of unclear, I used several passages from the first three chapters of Ezekiel to get the piont across. You can read it here. But basically he just saw the full glory of the Lord, God lifts him up, tells him to eat a delicous scroll, speaks to him, takes him to a certain place, and Ezekiel is upset. Why? If that happened to me, that would be the best day of my life! How on earth could he be upset about it?
