Ezekiel, through a vision, is seeing action in Jerusalem. This included, in the last chapter, the people of Jerusalem being killed by six armed men, six supernatural "guards."
Ezekiel 10:1-2, Scatter coals
I looked, and I saw the likeness of a throne of sapphire above the expanse that was over the heads of the cherubim. The LORD said to the man clothed in linen, "Go in among the wheels beneath the cherubim. Fill your hands with burning coals from among the cherubim and scatter them over the city." And as I watched, he went in.
Ezekiel sees the throne of sapphire above the expanse, which itself is above the cherubim of the altar. YHWH tells a figure clothed in linen (who previously had the writing kit) to fill his hands with burning coals and spread them out over the city of Jerusalem.
The cherubim were not mild, babylike creatures, but terrifying supernatural creatures, apparently viewed as guardians of the throne of YHWH.
Ezekiel 10:3-5, Moving to the threshold
Now the cherubim were standing on the south side of the temple when the man went in, and a cloud filled the inner court. Then the glory of the LORD rose from above the cherubim and moved to the threshold of the temple. The cloud filled the temple, and the court was full of the radiance of the glory of the LORD. The sound of the wings of the cherubim could be heard as far away as the outer court, like the voice of God Almighty when he speaks.
The physical manifestation of YHWH is on the move. The glory of God is now on the south side of the temple and His cloud fills the inner court of the temple. God's glory shines throughout the temple and the flapping wings of the cherubim are loud enough to to be heard in the outer court of the temple. This is "like the voice of God."
Ezekiel 10:6-8, Take fire
When the LORD commanded the man in linen, "Take fire from among the wheels, from among the cherubim," the man went in and stood beside a wheel. Then one of the cherubim reached out his hand to the fire that was among them. He took up some of it and put it into the hands of the man in linen, who took it and went out. (Under the wings of the cherubim could be seen what looked like the hands of a man.)
Fire is delivered to the man in linen from one of the cherubim within the wheels.
Ezekiel 10:9-14, Whirling wheels (again)
I looked, and I saw beside the cherubim four wheels, one beside each of the cherubim; the wheels sparkled like chrysolite. As for their appearance, the four of them looked alike; each was like a wheel intersecting a wheel. As they moved, they would go in any one of the four directions the cherubim faced; the wheels did not turn about as the cherubim went. The cherubim went in whatever direction the head faced, without turning as they went. Their entire bodies, including their backs, their hands and their wings, were completely full of eyes, as were their four wheels. I heard the wheels being called "the whirling wheels." Each of the cherubim had four faces: One face was that of a cherub, the second the face of a man, the third the face of a lion, and the fourth the face of an eagle.
Beside the cherubim appear the four wheels again. Here they are called "the whirling wheels."
Ezekiel 10:15-19, Moving to the entrance of the temple
Then the cherubim rose upward. These were the living creatures I had seen by the Kebar River. When the cherubim moved, the wheels beside them moved; and when the cherubim spread their wings to rise from the ground, the wheels did not leave their side. When the cherubim stood still, they also stood still; and when the cherubim rose, they rose with them, because the spirit of the living creatures was in them.
Then the glory of the LORD departed from over the threshold of the temple and stopped above the cherubim. While I watched, the cherubim spread their wings and rose from the ground, and as they went, the wheels went with them. They stopped at the entrance to the east gate of the LORD's house, and the glory of the God of Israel was above them.
God's presence moves to the entrance of the east gate of the temple.
Ezekiel 10:20-22, Same cherubim as before
These were the living creatures I had seen beneath the God of Israel by the Kebar River, and I realized that they were cherubim. Each had four faces and four wings, and under their wings was what looked like the hands of a man. Their faces had the same appearance as those I had seen by the Kebar River. Each one went straight ahead.
The vision's connection to the vehicle in chapter 1 is made clear -- they are the same. Under the faces and wings is something like a man's hands.
