Which language(s) of Jesus?
With the Hebrew speaking Moses and Elijah?
They were glorious to see. And they were speaking about his exodus [ἔξ οδος] from this world, which was about to be fulfilled in Jerusalem.
And he said, Abba [Ἀββᾶ], Father, all things are possible unto thee; take away this cup from me: nevertheless not what I will, but what thou wilt.
With an unnamed goyish Canaanite woman?
He answered, “It isn’t right to take the children’s bread and throw it to their dogs.”
With the Official Latin-Speaking Prefect of Rome?
Pilate asked him, “So you are a king?” Jesus replied, “You’re correct in saying [σὺ λέγεις] that I’m a king. I have been born and have come into the world for this reason: to testify to the truth. Everyone who belongs to the truth listens to me.”
