Judaism emphasizes language and symbols in its rituals and worldview. Key aspects include only speaking or writing the name of God in religious contexts due to its emphasis on language, avoiding images of God which stems from the second commandment prohibiting idol worship, and important symbols like the Shield of David, the Shema prayer, mezuzahs on doorposts, artifacts from the Tabernacle and Temple like the Ark of the Covenant and menorahs used in rituals.
