In the context of the Bible, "Two Chains" primarily refers to the chains used in the construction of the High Priest's breastplate as described in the Old Testament. These chains were an integral part of the priestly garments, which held significant religious and symbolic meaning for the Israelites.

Biblical References:

1. Exodus 28:14 : "and two chains of pure gold; you are to make them of braided cord work, and attach these chains to the settings." This verse is part of the detailed instructions given by God to Moses regarding the making of the High Priest's garments. The chains were to be made of pure gold and crafted with braided cord work, signifying the importance and sacredness of the High Priest's role.

2. Exodus 39:15-18 : "For the breastpiece they made braided chains of pure gold cord. They also made two gold filigree settings and two gold rings, and fastened the two rings to the two corners of the breastpiece. Then they fastened the two gold chains to the two gold rings at the corners of the breastpiece. They fastened the other ends of the two chains to the two filigree settings, and attached them to the shoulder pieces of the ephod at the front." This passage describes the actual construction of the breastplate, emphasizing the craftsmanship and the use of gold, which reflects the divine nature of the priestly duties.

Symbolism and Significance:

The two chains of gold were not merely functional but also carried deep symbolic meaning. They represented the connection between God and His people, with the High Priest serving as the mediator. The use of gold, a precious and incorruptible metal, symbolized purity, holiness, and the eternal nature of God's covenant with Israel.

The breastplate, to which the chains were attached, contained the Urim and Thummim, tools used for divine decision-making. This further underscores the chains' role in linking the divine will with the earthly realm, as the High Priest sought guidance from God on behalf of the nation.

Theological Implications:

From a theological perspective, the two chains can be seen as a foreshadowing of the New Testament's teaching on Christ as the ultimate High Priest. Just as the chains connected the breastplate to the ephod, Christ connects humanity to God, serving as the eternal mediator. Hebrews 4:14-16 speaks of Jesus as the great High Priest who has passed through the heavens, emphasizing His role in bridging the gap between God and mankind.

Historical Context:

In ancient Israel, the High Priest held a position of great authority and responsibility. The garments, including the breastplate and its chains, were designed according to divine specifications to ensure that the High Priest was properly attired to enter the Holy of Holies and perform his sacred duties. The meticulous attention to detail in the construction of these garments reflects the seriousness with which the Israelites approached their covenant relationship with God.

In summary, the "Two Chains" in the Bible are a testament to the intricate design and profound symbolism of the High Priest's garments, highlighting the sacred role of the priesthood in mediating between God and His people.
