Answer 1

It's only for Jews to know.

The fact that you use the offensive term for the Torah tells me you aren't a person I should tell.

Answer 2

The laying on of hands is a religious practice found throughout the world in varying forms. In Christian churches, this practice is used as both a symbolic and formal method of invoking the Holy Spirit during baptisms, healing services, blessings, and ordination of priests, ministers, elders, deacons, and other church officers, along with a variety of other church sacraments and holy ceremonies.

In a larger context, the Christian tradition of the laying on of hands has its roots in Jewish beliefs and practices. In biblical times the laying on of hands was an action which conferred blessing or authority. To wit, Isaac blessed his son Jacob by laying hands, and Aaron transferred the sins of the people of Israel to a sacrificial goat. (Leviticus 16:21.) Finally, in the Old Testament priests were ordained by the laying on of hands.

In the New Testament the laying on of hands was associated with the receiving of the Holy Spirit (See Acts 8:14-19). Initially the Apostles laid hands on new believers as well as believers who were called to a particular service. (See Acts 6:5). In the early Christian church, the practice was also used in ordination ceremonies and is still used in a wide variety of church ceremonies, such as the ceremony of confirmation, where a bishop, priest, or minister lays hands on the confirmand and prays for him to receive the Holy Spirit. Many churches also lay hands on a person when commissioning them to particular work, such as missionary or pastoral service.
