Christians believe that it was the Holy Spirit whom Jesus mentioned as the promised "Comforter" (i.e. "strengthener", "fortifier") in John 14:26. After his [[Resurrection of Jesus|resurrection]], Christ told his disciples that they would be "[[baptism|baptized]] with the Holy Ghost", and would receive power or endowment (Acts 1:4-8); a promise that was fulfilled in the events recounted in the second chapter of Acts. On the first [[Pentecost]], Jesus' disciples were gathered in Jerusalem when a mighty wind was heard and tongues of fire appeared over their heads. A multilingual crowd heard the disciples speaking, and each of them heard them speaking in his or her native language.
