Serious question about Jesus?

. We have no certain way of knowing whether he could speak Greek or Latin, but in his teaching ministry he regularly used either Aramaic or the highly Aramaized popular Hebrew. When Paul addressed the mob in the Temple, it is said that he spoke Hebrew (Acts 21:40). Scholars generally have taken this to mean Aramaic, but it is quite possible that a popular Hebrew was then the common tongue among the Jews.”—Biblical Archaeology, 1963, p. 243.......................It is possible that Jesus and his early disciples, such as the apostle Peter, at least at times spoke Galilean Aramaic, Peter being told on the night Christ was taken into custody: “Certainly you also are one of them, for, in fact, your dialect gives you away.” (Mt 26:73) ...........Jesus Christ as a man on earth could well have used a form of Hebrew and a dialect of Aramaic
