How was it "Asuy Keruvim v'Simorim"?
1.
Rashi: The cedar was illustrated with Keruvim and date trees.
2.
Malbim: The forms of Keruvim and date trees protruded from the wood; a thin layer of gold was flattened onto them, like it says "va'Yared Al ha'Keruvim v'Al ha'Simoros Es ha'Zahav" (Melachim I, 6:32).

What two faces were on the Keruv?
1.
Rashi: One was a young lion, and one was a human face. They faced in opposite directions. When the date tree was between two Keruvim, the lion faced it on one side, and the human face on the other side (19).
