Funny, I understood that Jesus actually talked in Aramaic. But he must have understood Greek, because there was no evidence of a translator when he was talking to Pontius Pilate.
Because of the Hellenization of the world, anyone who was in business or dealt with the Romans spoke Greek. Jesus was a carpenter with his father Joseph, and at that time Tiberias was being built on the sea of Galilee. I wonder if they went there for work and both had to learn Greek? Just some speculation.

Say it in your heart language, and believe in him. He is Immanuel, which literally means in Hebrew, "God with us." That is the most important part to remember. Also the Lamb of God, the Lion of Judah etc.
Henry Blackaby wrote a marvelous book on the names of God, including all the references. "Experiencing God." Not about experience, so much as how we have come to know Jesus and that he satisfies all our needs and hopes and dreams and desires.
