Ezekiel Ten - Cherubim Cherubims

"Each one had four faces: the first face was the face of a cherub, the second face the face of a man, the third the face of a lion, and the fourth the face of an eagle. And the cherubim were lifted up. This was the living creature I saw by the River Chebar," Ezekiel 10:14-15, NKJV. #CherubimCherubims
There seems to be various interpretations of the plurality or singularity, among many other things, surrounding cherubim as mentioned in the scriptures; for example, there are four distinct parts to one and sometimes the word is capitalized.
Genesis 3:22-24, Psalm 99:1 and Hebrews 9:1-5.
