The scroll of Yechezk'el (Ezekiel) was written by the prophet Yechezk'el (Ezekiel). Yechezk'el was taken to Bavel (Babylon) (now Iraq) during the second deportation. This was 597 BC. Yechezk'el means, "Strengthened by G-d".
M'lakhim Bet (2 Kings) 24:10-16 At that time the servants of N'vukhadnetzar (Nebuchadnezzar) king of Bavel (Babylon) went up to Yerushalayim (Jerusalem), and the city came under siege. And N'vukhadnetzar (Nebuchadnezzar) the king of Bavel (Babylon) came to the city, while his servants were besieging it. And Y'hoyakim (Jehoiachin) the king of Y'hudah (Judah) went out to the king of Bavel (Babylon), he and his mother and his servants and his captains and his officials. So the king of Bavel (Babylon) took him captive in the eighth year of his reign. And he carried out from there all the treasures of the house of the L-RD, and the treasures of the king's house, and cut in pieces all the vessels of gold which Shlomo (Solomon) king of Israel had made in the temple of the L-RD, just as the L-RD had said. Then he led away into exile all Yerushalayim (Jerusalem) and all the captains and all the mighty men of valor, ten thousand captives, and all the craftsmen and the smiths. None remained except the poorest people of the land. So he led Y'hoyakim (Jehoiachin) away into exile to Bavel (Babylon); also the king's mother and the king's wives and his officials and the leading men of the land, he led away into exile from Yerushalayim (Jerusalem) to Bavel (Babylon). And all the men of valor, seven thousand, and the craftsmen and the smiths, one thousand, all strong and fit for war, and these the king of Bavel (Babylon) brought into exile to Bavel (Babylon). NAS
Yechezk'el 1:1-3 Now it came about in the thirtieth year, on the fifth day of the fourth month, while I was by the river K'var (Chebar) among the exiles, the heavens were opened and I saw visions of G-d. (On the fifth of the month in the fifth year of King Y'hoyakhin's (Jehoiachin's) exile, the word of the L-RD came expressly to Yechezk'el (Ezekiel) the priest, son of Buzi, in the land of the Kasdim (Chaldeans) by the river K'var (Chebar); and there the hand of the L-RD came upon him.)
The thirtieth year - this was most likely when Yechezk'el was 30 years old. Normally a priest began His priestly duties when he was 30 years old. At this time Yechezk'el was called to be a prophet. So Yechezk'el began his ministry in 593/592 BC during the 5th year of his exile.
Visions of HaShem. False prophets were telling the people that they would not be in Babylon for long. They were false because they were in Babylon for Seventy years.
The first Hebrew letter is Aleph - head, as in Creator, King; the head of a bull appointed for sacrifice.
Yechezk'el 1:4-14 And as I looked and saw a windy storm was coming from the north, a great cloud with fire flashing forth continually and a bright light around it, and in its midst something like glowing metal in the midst of the fire. And within it there were figures resembling four living beings. And this was their appearance: they had human form. Each of them had four faces and four wings. And their legs were straight and their feet were like a calf's hoof, and they gleamed like burnished bronze. Under their wings on their four sides were human hands. As for the faces and wings of the four of them, their wings touched one another; their faces did not turn when they moved, each went straight forward. As for the form of their faces, each had the face of a man, all four had the face of a lion on the right and the face of a bull on the left, and all four had the face of an eagle (toward the rear). Such were their faces. Their wings were spread out above; each had two touching another being, and two covering their bodies. And each went straight forward; wherever the spirit was about to go, they would go, without turning as they went. In the midst of the living beings there was something that looked like burning coals of fire, like torches darting back and forth among the living beings. The fire was bright, and lightning was flashing from the fire. And the living beings ran to and fro like bolts of lightning.
Four living creatures called Cherubim. HaSatan was a Cherub that covered the throne of HaShem before he sinned against G-d and was booted out of heaven.
They have four faces and four wings. We also see their two wings touching one another and two wings covering their bodies. This is what the mercy seat on the arc is pointing to in heaven. They gleamed like burnished bronze -probably amber or brownish -gold. Light around the fire was probably the Shekinah glory.
The angels have an appearance of a man. This represents the Messiah's Yeshua human nature. This also corresponds to the scroll of Luke where we see His human nature stressed. Their bronze feet represent His bronze feet and His judgment. We see these feet mentioned in Revelation.
Colossians 1:13-18 For He delivered us from the domain of darkness, and transferred us to the kingdom of His beloved Son, in whom we have redemption, the forgiveness of sins. And He is the "EXACT LIKENESS" of the invisible G-d, the first-born of all creation. For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities-- all things have been created by Him and for Him. And He is before all things, and in Him all things hold together. He is also head of the body, the believers; and He is the beginning, the first-born from the dead; so that He Himself might come to have first place in everything. For it was the Father's good pleasure for all the fullness to dwell in Him, and through Him to reconcile all things to Himself, having made peace through the blood of His execution stake; through Him, I say, whether things on earth or things in heaven.
