And these signs shall follow them that believe;
In my name shall they cast out devils;
they shall speak with new tongues;
Mark 16:17
Adam Clarke
Charles Spurgeon
Matthew Henry
These signs shall follow - Or rather, accompany; this is the proper import of the original word παρακολουθησει, from παρα with, and ακολουθεω, I follow.
Them that believe - The believers, as we express it; i.e. the apostles, and all those who in those primitive times were endued with miraculous powers, for the confirmation of the doctrines they preached.
In my name - That is, by the authority and influence of the almighty Jesus.
Cast out devils - Whose kingdom Jesus Christ was manifested to destroy.
Speak with new tongues - This was most literally fulfilled on the day of pentecost, Acts 2:4-19.
They shall speak with new tongues, which they had never learned, or been acquainted with and this was both a miracle (a miracle upon the mind), for the confirming of the truth of the gospel, and a means of spreading the gospel among those nations that had not heard it.
