Definition and Scope:
In the biblical context, "authority given" refers to the power or right bestowed upon individuals by God to act on His behalf, execute His will, and lead others according to His purposes. This authority is often associated with leadership, teaching, healing, and governance within the community of believers and the broader world.

Old Testament Context:
In the Old Testament, authority is often conferred by God to leaders, prophets, and kings. For instance, Moses is given authority to lead the Israelites out of Egypt (Exodus 3:10). God tells Moses, "So now, go. I am sending you to Pharaoh to bring My people the Israelites out of Egypt" (Exodus 3:10). Similarly, Joshua is granted authority to lead the Israelites into the Promised Land after Moses' death (Joshua 1:1-9).

The authority of kings, such as David and Solomon, is also depicted as divinely sanctioned. David is anointed by Samuel at God's command (1 Samuel 16:12-13), and Solomon is granted wisdom and authority to rule Israel (1 Kings 3:12-13).

New Testament Context:
In the New Testament, authority is a central theme in the ministry of Jesus Christ and the early Church. Jesus Himself is depicted as having divine authority. In Matthew 28:18, Jesus declares, "All authority in heaven and on earth has been given to Me" . This authority is evident in His teachings, miracles, and His power over nature and demons.

Jesus also delegates authority to His disciples. In Luke 9:1-2, He "called the Twelve together and gave them power and authority over all demons, and power to cure diseases" . This authority is not only for miraculous works but also for preaching the Kingdom of God.

The Great Commission in Matthew 28:18-20 further emphasizes the transfer of authority to the disciples, as Jesus commands them to "go and make disciples of all nations" , baptizing and teaching them to obey His commands.

Apostolic Authority:
The apostles, as foundational leaders of the early Church, are depicted as having received authority from Christ. Paul, in his letters, often defends his apostolic authority as being directly from Jesus Christ (Galatians 1:1). This authority is exercised in teaching, church discipline, and the establishment of church doctrine.

Authority in the Church:
The New Testament also outlines the structure of authority within the Church. Elders and overseers are given authority to shepherd the flock and maintain doctrinal purity (1 Timothy 3:1-7, Titus 1:5-9). This authority is seen as a stewardship from God, requiring humility and service rather than domination (1 Peter 5:1-3).

Spiritual Authority:
Believers are also described as having spiritual authority in Christ. Ephesians 2:6 states that God "raised us up with Him and seated us with Him in the heavenly realms in Christ Jesus" , indicating a position of authority in the spiritual realm. This authority is exercised through prayer, spiritual warfare, and living a life that reflects the Kingdom of God.

Conclusion:
The concept of "authority given" in the Bible underscores the divine origin of true authority and its purpose for advancing God's kingdom on earth. It is a responsibility that requires obedience, humility, and alignment with God's will, as demonstrated by the leaders, prophets, apostles, and believers throughout Scripture.
