The answer
Agree. Aramaic was the common spoken language of first-century Galilee, and the Gospels even preserve his Aramaic words — "Talitha koum" (Mark 5:41) and the cry from the cross (Mark 15:34). Hebrew and Greek were also in use in his environment: Hebrew remained a living language in some Judean circles, and Greek was widespread in Galilee and the Decapolis.
Why it’s interesting
So sayings we read in Greek stand at some remove from a Galilean's Aramaic. Those few Aramaic phrases the Gospels kept are striking — though they don't mean the Greek text is a word-for-word translation of remembered Aramaic throughout.
