Ezek. 41:18:KJV And it was made with cherubims and palm trees, so that a palm tree was between a cherub and a cherub; and every cherub had two faces;
Verses 19-25 reveal that one of these two faces was of a “man” and the other face was of a “young lion”:
So that the face of a man was toward the palm tree on the one side, and the face of a young lion toward the palm tree on the other side: it was made through all the house round about. ...
We also know that there were only two faces, one on each cherub overlooking the mercy seat of the earthly tabernacle as revealed in Exodus 25:18-22. Moreover, there is much reason to believe that the cherubim of the earthly temples had no more than two faces, and that they were no different faces than that of the “man” and the “young lion”.
However, In Ezek. 1:1, the heavens were opened up and the prophet saw visions of God. Moreover, he saw four creatures, each having four faces, not two. Ezek. 5:10 described them:
As for the likeness of their faces, they four had the face of a man, and the face of a lion, on the right side: and they four had the face of an ox on the left side; they four also had the face of an eagle.
So paired up on the right side was the same two faces that showed up in the earthly dwelling places, and on the left side they each had the face of an ox and an eagle.
Likewise, John was shown the throne in heaven, and in Rev 4:6-7 four beasts, each having a certain likeness, or face. Again, the four different faces were like a lion, a calf, a man and a flying eagle.
And before the throne there was a sea of glass like unto crystal: and in the midst of the throne, and round about the throne, were four beasts full of eyes before and behind. And the first beast was like a lion, and the second beast like a calf, and the third beast had a face as a man, and the fourth beast was like a flying eagle.
So what does the mean that only the face of the man and the face of the lion seem to apply to the earthly dwelling place of the LORD during His millennial reign, as well as to the prior earthly tabernacle and temples, whereas the heavenly throne shows four faces are required to be in connection with the heavenly throne.
