### Core Meaning & Semantic Range
The Hebrew word **ʼachlâmâh**, represented by `{{H306}}`, is a gem, identified as the **amethyst**. Its name is perhaps derived from a root word meaning "to dream," suggesting a "dream-stone." This specific term appears only **2 times** across **2 unique verses** in the Bible, both times in the context of the priestly garments.
### Biblical Occurrences & Contextual Analysis
In the biblical narrative, `{{H306}}` is mentioned exclusively as one of the precious stones set into the high priest's breastplate. Both occurrences are nearly identical, listing it as the final stone in the third row. It is named alongside the ligure and the agate, establishing its place within a meticulously ordered, divinely commanded design ([[Exodus 28:19]], [[Exodus 39:12]]).
### Related Words & Concepts
Several related words help define the context in which **ʼachlâmâh** is found:
* `{{H2905}}` **ṭûwr** (a row; hence, a wall; row): This word establishes the physical arrangement of the amethyst on the breastplate, which was organized into four distinct rows of stones [[Exodus 28:19]].
* `{{H3958}}` **leshem** (a gem, perhaps the jacinth; ligure): This gem, the ligure, is listed directly beside the amethyst in the third row of the breastplate [[Exodus 39:12]].
* `{{H7618}}` **shᵉbûw** (a gem (from its sparkle), probably the agate; agate): The agate is another gemstone that appears with the amethyst in the same grouping on the priestly garment [[Exodus 28:19]].
* `{{H7992}}` **shᵉlîyshîy** (third; feminine athird (part); by extension, a third (day, year or time); specifically, a third-story cell); third (part, rank, time), three (years old): This ordinal number specifies the exact position of the **row** `{{H2905}}` containing the amethyst [[Exodus 39:12]].
### Theological Significance
The significance of `{{H306}}` is derived entirely from its prescribed role in the sacred vestments of the high priest.
* **Divine Specification:** The inclusion of the **amethyst** was not a matter of choice but a direct command from God as part of the instructions for the holy garments [[Exodus 28:19]].
* **Symbol of Order:** Its consistent placement as the last stone in the **third** `{{H7992}}` **row** `{{H2905}}` underscores the importance of precision and order in the articles consecrated for tabernacle worship.
* **Part of a Consecrated Whole:** The **amethyst** functions as an integral component of the breastplate, a key element of the high priest's attire used when ministering before the Lord.
### Summary
In summary, **ʼachlâmâh** `{{H306}}` refers specifically to the **amethyst**. Its biblical importance is not found in a wide range of uses but in its very specific and unalterable placement on the high priest's breastplate. The term illustrates how even a rarely mentioned object has profound significance when it is part of a divinely mandated design for worship, representing order, consecration, and obedience to God's detailed instructions.
