A “Hebraism” is a typical feature of the Hebrew language found in another language. The majority of today’s New Testament authorities assume that Aramaic is behind the Semitisms of the New Testament, and that Jesus spoke Aramaic as his primary language. So much so, in fact, that the student who checks standard reference works is informed that the Greek words for “Hebrew” and for “in the Hebrew language” (not only in the New Testament, but in Josephus and other texts) refer to the Aramaic language.
Jesus made bold messianic claims when he spoke. To thoroughly understand these claims, however, we must get into a time machine and travel back in time to a completely different culture, the Jewish culture of first-century Israel. We must acculturate ourselves to the way teachers and disciples in the time of Jesus communicated through allusions to Scripture.
The Feast of Tabernacles (or Sukkot or Festival of Booths) as celebrated during the late Second Temple era included elements which were not prescribed in Scripture, and some of which ended with the destruction of the Temple.
In a beautiful statement that probably referred to the Kingdom of Heaven, Jesus proclaimed to his disciples, according to Luke, that “many prophets and kings” desired to see and hear what they (his disciples) are seeing and hearing. Matthew preserves the same saying, but in Matthew’s account the doublet is, “prophets and righteous persons.” The wording of Jesus’ saying in these two accounts is so similar that it appears likely that their slight differences reflect literary, or editorial, changes rather than different versions of the saying uttered by Jesus on different occasions. If so, which of these gospel accounts preserves the more original form of Jesus’ saying? Did Jesus say “prophets and kings” or “prophets and righteous persons”?
There is a common thread uniting the views of those who think that Jesus signaled Daniel 7 by using the Aramaic bar enash in the middle of Hebrew speech. Anyone who holds this view must assume that Jesus spoke or taught in Hebrew much of the time. That Jesus used Hebrew a significant amount of the time is a sociolinguistic conclusion that has a growing number of supporters in New Testament scholarship, but one that is still a minority opinion.
