Although we commonly say that the Old Testament was written in Hebrew, we know that portions of Ezra and Daniel were written in Aramaic. We also know that there are a few Aramaic words in the New Testament (Abba, Cephas, Maranatha, etc.). Benjamin D. Suchard has translated Holger Gzella’s Aramaic: A History of the First World Language (2017) and Eerdmans has recently published it (2021). You may not be as into languages as I am, but I think this is a fascinating book. The most important chapter, of course, is chapter 4, “Aramaic in the Bible and Early Judaism.”
