These Hebrew terms similarly reflect the act of confining or imprisoning individuals, often in a legal or punitive context, and are used in the Old Testament to describe similar actions taken against individuals.

Usage: The verb φυλακίζω is used in the New Testament to describe the act of confining or imprisoning someone. It is often used in the context of legal or punitive actions taken against individuals, particularly in the context of early Christian persecution.

Context: The term φυλακίζω appears in the New Testament in contexts where individuals are physically confined or imprisoned. This action is often a result of legal proceedings or as a consequence of preaching the Gospel. The act of imprisoning is depicted as a tool used by authorities to suppress dissent or maintain order, particularly against those spreading the Christian faith.

In the New Testament, φυλακίζω is used to describe the imprisonment of key figures such as the apostles. For example, in Acts 5:18, the apostles are arrested and put in the public jail for preaching about Jesus: "They arrested the apostles and put them in the public jail." This reflects the broader theme of persecution faced by early Christians, who were often imprisoned for their beliefs and teachings.

The use of φυλακίζω highlights the tension between the nascent Christian movement and the established religious and political authorities of the time. Imprisonment served as a means to deter the spread of Christianity, yet it often resulted in further dissemination of the faith as imprisoned believers continued to witness to others.
