The Day of Pentecost: Lesson Three
The Holy Ghost came with speaking in other tongues.
They were all filled with the Holy Ghost, and every one of them spoke with other tongues as the Spirit gave them utterance.
Acts 2:4 (KJV): And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
This was the promise Jesus told them to wait for, and it did not end on that one day. Later in Ephesus, the Holy Ghost came again and they spoke with tongues.
Acts 19:6 (KJV): And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.
