Biblical References:
Ram skins dyed red are mentioned in the context of the construction of the Tabernacle, the portable dwelling place for the presence of God among the Israelites during their journey through the wilderness. The primary references to ram skins dyed red can be found in the Book of Exodus.

Exodus 25:5 : "ram skins dyed red and fine leather; acacia wood;"

Exodus 26:14 : "Also make a covering for the tent out of ram skins dyed red, and over that a covering of fine leather."

Exodus 35:7 : "ram skins dyed red and fine leather; acacia wood;"

Exodus 36:19 : "Additionally, he made for the tent a covering of ram skins dyed red, and over that a covering of fine leather."

Exodus 39:34 : "the covering of ram skins dyed red, the covering of fine leather, and the veil of the covering;"

Exodus 40:19 : "Then he spread the tent over the tabernacle and put the covering over the tent, just as the LORD had commanded him."

Symbolism and Significance:
In the construction of the Tabernacle, the use of ram skins dyed red held both practical and symbolic significance. Practically, the ram skins provided a durable and weather-resistant covering for the Tabernacle, protecting the sacred space from the elements. The dyeing of the skins red may have been intended to enhance their durability and aesthetic appeal.

Symbolically, the color red in the Bible often represents sacrifice, atonement, and redemption. The ram, as an animal, is associated with sacrifice, as seen in the account of Abraham and Isaac, where a ram is provided by God as a substitute sacrifice (Genesis 22:13). The red dye could thus symbolize the blood of sacrifice, pointing forward to the ultimate sacrifice of Jesus Christ, whose blood would atone for the sins of humanity.

Theological Implications:
The use of ram skins dyed red in the Tabernacle's construction underscores the theme of atonement and the necessity of sacrifice for the presence of God to dwell among His people. The Tabernacle itself is a foreshadowing of the coming of Christ, who "tabernacled" among us (John 1:14) and whose sacrificial death and resurrection would fulfill the requirements of the Law and provide a way for humanity to be reconciled to God.

Historical and Cultural Context:
In the ancient Near East, the use of animal skins for tents and coverings was common due to their availability and durability. The process of dyeing skins, particularly in vibrant colors like red, would have been a skilled craft, indicating the care and precision involved in the construction of the Tabernacle. The Israelites, having left Egypt, would have been familiar with such practices, as Egypt was known for its advanced techniques in dyeing and leatherwork.

Conclusion:
The inclusion of ram skins dyed red in the Tabernacle's design reflects the intricate and purposeful nature of God's instructions to Moses. Each element of the Tabernacle served not only a functional role but also a deeper spiritual purpose, pointing to the holiness of God and the means by which He would ultimately redeem His people.
