The answer is: Rams

Exo 25:5

In the book of Exodus, the use of ram skins dyed red in the construction of the tabernacle serves a practical and symbolic purpose. Rams, known for their strength and endurance, were significant animals in ancient societies, often associated with sacrifice and leadership. Whispers of their symbolic nature can be discovered in various mentions across the Bible—as in Genesis, when Abraham offers a ram as a substitution for his son Isaac, reinforcing concepts of redemption.

The very idea of dyed skins speaks to the artistry and craftsmanship present in biblical times. Craftspersons didn't just throw together materials; they infused their work with meaning and effort. The Tabernacle—essentially a mobile temple—underscored the importance of God's presence among His people. Each component, like the ram skins, patched together a deeper understanding of divinity that reaches beyond physical barriers.

Through ages, the shedding of blood, whether from the ram or other sacrifices, becomes a recurrent theme, unstitching reliability and community into stories of vulnerability, forgiveness, and atonement. Fun fact: the phrase "dyed red" might remind you of other significant 'red' moments in the Bible, like the red dye affixed to Joshua and Rahab's story as a signal of protection. Therefore, rams were not just a literal offering; they represent myriad connections tracing through the colorful tapestry of Biblical themes—sacrifice, protection, and divine orchestration.
