It goes on to say in verses 5–11 that when the Apostles spoke, each person in attendance "heard their own language being spoken". Therefore, the gift of speaking in tongues refers to the Apostles' speaking languages that the people listening heard as "them telling in our own tongues the mighty works of God". Glossolalists and cessationists both recognize this as xenoglossia, a miraculous ability that marked their baptism in the Holy Spirit.
