Cherubim

Genesis 3:24 says of that God placed "on the east side of the Garden of Eden cherubim and a flaming sword flashing back and forth to guard the way to the tree of life."

The Hebrew word Kerub is translated by some scholars as "one who intercedes" and by others as "knowledge." The original Karibu were the terrible and monstrous guardians of the temples and palaces in Sumer and Babylon. There were also similar guardians in the Near East, and there were winged, eagle-headed deities that guarded an Assyrian Tree of Everlasting Life.

They are said to have 4 wings and 4 faces. Exodus 25 talks of how the Ark was to be decorated with Cherubim, while 1 Samuel 4:4 says that the Lord is "enthroned between the cherubim" on the Ark. Psalms 18:10 speaks of the Lord, who "mounted the cherubim and flew; he soared on the wings of the wind."

Ezekiel describes them as such:

"They had the figures of human beings. However, each had four faces, and each of them had four wings; the legs of each were [fused into] a single rigid leg, and the feet of each were like a single calf's hoof; and their sparkle was like the luster of burnished bronze.

They had human hands below their wings. The four of them had their faces and their wings on their four sides. Each one's wings touched those of the other. They did not turn when they moved; each could only move in the direction of any of its faces.

Each of them had a human face [at the front]; each of the four had the face of a lion on the right; each of the four had the face of an ox on the left; and each of the four had the face of an eagle [at the back]. Such were their faces. As for their wings, they were separated: above, each had two touching those of the others, while the other two covered its body." - Ezekiel 1:5-11
