In the context of biblical references, the term "porpoise" is often associated with the materials used in the construction of the Tabernacle, as described in the Old Testament. The Revised Version (RV) margin notes suggest "porpoise" as a possible translation for the Hebrew word "תַּחַשׁ" (tachash), which appears in several passages related to the Tabernacle's coverings.

Biblical References:

1. Exodus 25:5 · "ram skins dyed red and fine leather; acacia wood;"
2. Exodus 26:14 · "Also make for the tent a covering of ram skins dyed red, and over that a covering of fine leather."
3. Exodus 35:7 · "and ram skins dyed red and fine leather; acacia wood;"
4. Ezekiel 16:10 · "I clothed you with embroidered cloth and put sandals of fine leather on your feet. I wrapped you in fine linen and covered you with silk."

In these passages, the Berean Standard Bible translates the Hebrew word "tachash" as "fine leather." However, the exact nature of this material has been the subject of scholarly debate. Some translations and interpretations suggest that "tachash" could refer to the skin of a marine animal, such as a porpoise or dolphin, due to the waterproof qualities required for the outermost covering of the Tabernacle.

Historical and Cultural Context:

The use of marine animal skins, such as those from porpoises, would have been practical for the Israelites during their wilderness journey. These skins are known for their durability and water-resistant properties, making them suitable for protecting the sacred structure from the elements.

The identification of "tachash" as porpoise skin is supported by some historical accounts and linguistic studies, although it remains a topic of discussion among biblical scholars. The term may also refer to a now-extinct animal or a specific type of leather known to the ancient Israelites.

Symbolic Significance:

The use of such durable and protective materials for the Tabernacle's coverings underscores the importance of safeguarding the holy space where God's presence dwelt among His people. The layers of coverings, including the possible porpoise skin, symbolize the care and reverence with which the Israelites approached their worship and relationship with God.

In summary, while the exact identification of "tachash" remains uncertain, the suggestion of porpoise skin highlights the practical and symbolic considerations in the construction of the Tabernacle. The choice of materials reflects the Israelites' commitment to honoring God through their craftsmanship and attention to detail.Exodus 25:5
