The Holy Spirit!
During his teachings, Jesus spoke about the Holy Spirit as a comforter and helper who would guide and empower his followers. He emphasized the importance of receiving the Holy Spirit for spiritual guidance and strength.
Jesus spoke aramaic
The Holy Spirit is the comforter. He walks beside you when you are a believer.
Jesus spoke outdoors when he fed the five thousand, and spoke from a boat... etc
Comforter is another term applied to the Holy Spirit by Jesus.
The Comforter is the Holy Ghost. Spoken of by Jesus in John 14. The power promised to the Apostles who were to tarry in Jerusalem until they were emdued with power from on high
The Comforter, the Holy Ghost, as he promised: And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; (John 14.16)
Many scholars are in the general agreement that Jesus and His disciples spoke in the then common language in Jerusalem - Aramaic.
No Jesus spoke aramaic.
Jesus was refering to the holy spirit here , as the comforter.
Jesus was to send the Comforter who would comfort Christians and challenge the unbelievers.
The Bible never suggests that Jesus spoke in tongues. It is assumed that he always spoke in clear Aramaic.
