Only a few believers prior to the Church Age were endued with the Holy Spirit. They were given the power of the Holy Spirit to perform a special mission. The Enduement of the Holy Spirit was not permanent. It could be lost, as when David sinned with Bathshebah. David had to Rebound and pray to receive the Enduement back again.
The Enduement is different from the Filling of the Holy Spirit in the Church Age. In the Filling of the Holy Spirit, the Holy Spirit empowers and controls the soul of the Church Age believer. The Filling of the Holy Spirit is available to all Church Age believers. It is given at the moment of Salvation. It is lost when the believer sins, and it is regained through Rebound.
