'Languages' in the Bible

All of them were filled with the Holy Spirit and began to speak in foreign languages as the Spirit gave them that ability.

Cretans, and Arabs, listening to them talk in our own languages about the great deeds of God?"

because they heard them speaking in foreign languages and praising God. Then Peter said,

When Paul laid his hands on them, the Holy Spirit came on them, and they began to speak in foreign languages and to prophesy.
