This is the list of 10 principles of faith for Karaites printed in the book Petah Tikva (Constantinople 1831), which you can read or download at hebrewbooks.org here. (I know!) The book was intended for children.
The seventh is particularly interesting: "ובלשון העברי נתנה תורת האלהים ולכן חוב ללמוד ולהגות לשון התורה ובאורה," "In the Hebrew language was God's Torah given; therefore it is an obligation to learn and contemplate the language of the Torah and its explanations."
These come abstracted from Elijah Bashyazi's אדרת אליהו, in the section called עשרה עקרים. In the edition which I linked it is on page מח., although it is number 6, not 7, as in this list. I didn't look them over to compare them, although I'll do that later. Or eventually.
