I believe you mentioned that English isnt your first language...
Old(e) English is not my first language. When singing hymns in church I audibly change the thee’s and thou’s into their modern english counterpart. I consider it to be a foreign language, though similar to the language we speek. Kinda like Puerto Rico and Mexico both speak “Spanish”, but they are very different versions.

The KJV was translated near the end of the run for the use of thee and thou as personal pronouns, except for part of Scotland where apparently you can still hear it in daily conversation. It’s an inflected pronoun, I suppose it came over from German.
It amuses me that the book of Mormon borrows this pronoun form. Joseph Smith produces/translates his book around 1829 and for some reason his Golden Plates were fixated on Middle to Early Modern English. Maybe the plates knew it sounded “religious” to the modern ear even though it was just the everyday pronoun of its own era.
