What language was originally written in what language?

Answer 1

AnswerThe Book of Exodus was written in Hebrew.

Answer 2

Matthew's Gospel was originally written in Greek Koine.

This can be proven without any doubt, because the author of Matthew relied on Mark's Gospel for everything he knew about the life and mission of Jesus, and he frequently copied Mark's text word for word in the Greek language. Further evidence is that his second major source, for further sayings attributed to Jesus, was the hypothetical 'Q' document, which was also written in Greek. Finally, the author of Matthew relied on the Septuagint, an early and flawed Greek translation of the Hebrew scriptures, whenever he quoted Old Testament texts, indicating again that he was writing Greek.
