Linen garments hold significant importance in the biblical narrative, symbolizing purity, holiness, and divine service. Linen, a fabric made from the fibers of the flax plant, was highly valued in ancient times for its quality and durability. Its use in the Bible is often associated with sacred and priestly functions, as well as with wealth and nobility.

Priestly Garments:
Linen was the primary material used for the garments of the priests in the Old Testament. In Exodus 28:39-42, God commands Moses regarding the priestly attire: "You are to weave the tunic with fine linen, make the turban of fine linen, and fashion the sash with embroidery. Make linen undergarments to cover their bare flesh, extending from waist to thigh." These garments were to be worn by Aaron and his sons when ministering in the Tabernacle, symbolizing their consecration and purity before the Lord.

The high priest's attire also included a linen ephod, as described in 1 Samuel 2:18: "Now Samuel was ministering before the LORD—a boy wearing a linen ephod." The linen ephod was a distinctive garment that set the priests apart for their sacred duties.

Symbol of Righteousness and Purity:
Linen garments are frequently associated with righteousness and purity. In Revelation 19:8, the fine linen worn by the bride of Christ is described as "the righteous acts of the saints." This imagery underscores the spiritual significance of linen as a representation of holiness and moral purity.

Royal and Noble Use:
Linen was also a fabric of choice for royalty and the wealthy. In Proverbs 31:22, the virtuous woman is described as making "coverings for her bed; her clothing is fine linen and purple," indicating her prosperity and industriousness. Similarly, in Esther 8:15, Mordecai is adorned in "royal garments of blue and white, with a large crown of gold and a purple robe of fine linen," signifying his elevated status and honor.

Prohibition of Mixed Fabrics:
The Law of Moses prohibited the mixing of linen and wool in garments, as stated in Deuteronomy 22:11: "Do not wear clothes of wool and linen woven together." This commandment is often interpreted as a call to maintain purity and separation, reflecting the broader theme of holiness in the life of the Israelites.

Linen in Burial Practices:
Linen was also used in burial practices, as seen in the New Testament. Jesus' body was wrapped in linen cloths after His crucifixion, as recorded in Matthew 27:59: "So Joseph took the body, wrapped it in a clean linen cloth." This practice highlights the respect and honor given to the deceased, as well as the continued association of linen with purity.

In summary, linen garments in the Bible are rich with symbolic meaning, representing purity, holiness, and divine service. They are integral to the priestly functions, signify righteousness, and are associated with nobility and respect. The use of linen underscores the biblical themes of consecration and the call to live a life set apart for God.
