The Bible never records Jesus speaking in tongues because He already spoke the languages of His listeners. Jesus’ power to reach hearts came not through a spiritual gift but through His divine authority, perfect love, and ultimate sacrifice.
The Bible does not explicitly say that Jesus spoke in tongues. Some believe that Jesus’ sighs in Mark 7:34 and Mark 8:12 were the same as speaking in tongues. However, if Jesus had truly been speaking in tongues, the proper Greek terminology would reflect that. Moreover, speaking in tongues means to communicate with people in unfamiliar languages to edify them. This was unnecessary for Jesus since He spoke Aramaic and Hebrew (Mark 5:41; Acts 26:14) and probably Greek as others did in the region He was preaching in. Furthermore, in 1 Corinthians 14:6 Paul indicated that merely speaking in tongues is useless unless it is accompanied by “revelation,” “knowledge,” “prophecy” or “teaching.” Clearly, the gift of tongues was not what ultimately influenced the impact of Paul's ministry. Rather, it was the way God used him through godly character, leadership, and discipleship. A similar sentiment can be said of Jesus. His greatest impact came not from a spiritual gift but from His character and ultimately His sacrifice.
Some say that Jesus spoke in tongues because they believe that is what His sighing was in Mark 7:34 and Mark 8:12. However, this incorrect interpretation is an example of why we diligently consider context and definitions in the Greek and Hebrew language so we don’t misunderstand and misapply Scripture. In Greek, sighing and speaking in tongues differ. Regarding those aforementioned verses, sighing is the equivalent of groaning or lamenting rather than edifying people in a different language. Additionally, since Jesus was preaching in regions that were familiar with Aramaic, Hebrew, and Greek, why would He need to have spoken in tongues since He would logically preach in the same language of His listeners? Lastly, the Holy Spirit gave Jesus’ followers the gift of speaking in tongues after Jesus had ascended into heaven. This implies that the gift of speaking in tongues was not used until the pivotal event of Pentecost in Acts 2:1-4.
