Ezekiel 1:1-28, 3:12
The Torah describes the appearance of G-d at Sinai. It says that G-d came down in smoke and fire, there were the blasts of the shofar and thunder and lightning, and the entire mountain trembled. The Torah portion continues with the recitation of the Ten Commandments.
The haftarah begins with Ezekiel saying that the heavens opened and he saw visions of G-d. The depiction Ezekiel gives of the panorama of sound and light is quite incredible. He describes amazing sounds and flames, flashes of light and smoke.
He goes on to describe the creatures he saw. They were like flashes of flame. Each had four animal faces, 6 wings, and legs with hooves. They were balanced on a wheel within a wheel, and the wheels had eyes on them, all about.
The description in the haftarah is quite beautiful, amazing, and detailed.
