### Core Meaning & Semantic Range
The Hebrew word **shᵉchêleth**, represented by `{{H7827}}`, refers to **onycha**, a specific type of aromatic ingredient. It appears only **1 time** in the entire Bible. The base definition describes it as a "scale or shell, i.e. the aromatic mussel," and its origin may be related to an obscure idea of peeling off by a concussion of sound.
### Biblical Occurrences & Contextual Analysis

In [[Exodus 30:34]], the LORD commands Moses to take specific ingredients for this holy mixture: "Take unto thee sweet spices, stacte, and **onycha**, and galbanum; these sweet spices with pure frankincense: of each shall there be a like weight." This context establishes **onycha** as a key, divinely mandated component for worship in the Tabernacle.
