The theological weight of `{{G49}}` is understood through its connection to broader themes of sanctification and sacrifice.
* **Ceremonial Act:** The use of **hagnismós** in [[Acts 21:26]] points to a physical, observable ritual of cleansing tied to the temple and specific offerings. It represents an outward process required to demonstrate the fulfillment of a vow.
