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.
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).
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.
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.
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.
