The scriptures that make up the Old Testament were written in Hebrew, apart from Ezra 4:8 — 6:18 and 7:12-26 (67 verses), and Daniel 2:4b — 7:28 (200 verses) which were written in Aramaic.
The scriptures which make up the New Testament were written in Greek.
I hope you find this helpful.
God bless,
