The term "The Hidden Men" does not appear explicitly in the Bible, but it can be associated with various biblical themes and narratives that involve individuals or groups who are concealed, protected, or operate in secrecy for divine purposes. This concept can be explored through several scriptural accounts and theological interpretations.

Biblical Instances and Themes:

1. Elijah and the Prophets:
In 1 Kings 18, during the reign of King Ahab and Queen Jezebel, the prophet Elijah confronts the prophets of Baal. Prior to this confrontation, Obadiah, a devout believer in the LORD, hides one hundred prophets in two caves to protect them from Jezebel's persecution. "When Jezebel was killing off the prophets of the LORD, Obadiah had taken a hundred prophets and hidden them, fifty men to a cave, and had provided them with food and water" (1 Kings 18:4). This act of hiding the prophets illustrates the theme of divine preservation and protection of God's servants during times of apostasy and danger.

2. The Birth of Moses:
In Exodus 2, the birth and early life of Moses involve a period of concealment. When Pharaoh orders the death of all Hebrew male infants, Moses' mother hides him for three months. "But when she could hide him no longer, she got a papyrus basket for him and coated it with tar and pitch. Then she placed the child in it and set it among the reeds along the bank of the Nile" (Exodus 2:3). This act of hiding Moses is pivotal in God's plan for the deliverance of Israel from Egypt.

3. The Hidden Life of Jesus:
The early life of Jesus Christ, particularly the years before His public ministry, is often referred to as His "hidden years." After the flight to Egypt to escape King Herod's massacre (Matthew 2:13-15), Jesus grows up in Nazareth, living a life largely undocumented in the Gospels until His baptism by John. This period of concealment underscores the mystery and preparation for His redemptive mission.

4. The Remnant:
Throughout the Old Testament, the concept of a faithful remnant is prevalent. These are individuals or groups who remain true to God despite widespread unfaithfulness. Isaiah speaks of this remnant: "Though your people, O Israel, be like the sand of the sea, only a remnant will return" (Isaiah 10:22). The remnant is often hidden within the larger unfaithful population, preserved by God for future restoration.

5. The Church as a Hidden Mystery:
In the New Testament, the Church is described as a mystery hidden in ages past but revealed through Christ. Paul writes, "This mystery is that through the gospel the Gentiles are fellow heirs, fellow members of the body, and fellow partakers of the promise in Christ Jesus" (Ephesians 3:6). The Church, as the body of Christ, was a hidden plan now revealed, encompassing both Jews and Gentiles.

Theological Implications:

The concept of "The Hidden Men" can be seen as a metaphor for God's providential care and the unfolding of His divine plan, often concealed from human understanding. It highlights the themes of protection, preparation, and revelation. God's purposes are sometimes hidden from the world, yet they are always working towards the fulfillment of His promises. The hiddenness serves as a reminder of the sovereignty of God and the assurance that He is at work even when His actions are not immediately visible.
