The first furnishing of the Tabernacle that G-d instructed the Jews to make was the Ark of the covenant, an open, gold-covered wooden box that housed the two Tablets of the covenant upon which G-d had engraved the Ten Commandments. The Ark was sealed by a golden Cover, upon which were two figurines of winged angels with infant faces, known as cherubim.
You Must make two golden cherubim.
Exodus 25:18
The infant-like faces of the cherubim signified that our intrinsic bond with G-d is akin to the essential bond between parent and child. Despite and fluctuations that might arise in their relationship, the bond between parent and child can never be broken. The fact that the cherubim were situated above the Tablets of the Torah and faced each other signified that by studying Torah, we can reach the root of our Divine soul, allowing our consciousness to merge totally with G-d. The infant faces of the cherubim also alluded to the fact that the Torah, G-d's infinite wisdom. G-d contracted His infinite wisdom into a form we can understand and digest, much as an expert teacher contracts his grasp of a subject in order to convey it to his pupils.
The fact that the cherubim's wings were spread protectively over the Ark alludes to the fact that the Torah-education of young children ensures the preservation and continuity of the transmission of the Torah.
