Lutheran Latin Guide to the Hebrew Old Testament: Reineccius' Janua

Christian Reineccius, Janua Hebraeae Linguae Veteris Testamenti: in qua Totius Codicis Hebraei Vocabula una cum radicibus & Grammatica vocum difficiliorum analysi comparent (Lipsiae: Sumpt. Haered. Lanckisianorum, 1704).

Back in college (Concordia University Nebraska) I was blessed to learn Hebrew well from Dr. Mark Meehl, but as time goes on, you have to either use your language abilities or lose them! Hebrew is still there in the back of my mind somewhere, but since I work with Luther's German and Johann Gerhard's Latin nearly every day, that's much easier. 

To get back into reading the Hebrew Old Testament, I've found this book to be very helpful. It goes through the text verse by verse and gives the definition and form of every difficult Hebrew word, while also indicating the roots of most words. If your Latin is better than your Hebrew, and if you want a good free resource, try this!
