If someone were learning Biblical Hebrew or Greek for the first time, or wanted to brush up on them, what Logos resource(s) would you recommend? I'm using L5, if that helps. Thanks!
The Zondervan Biblical Languages bundle is the obvious starting point, I would think. It includes one of the standard Greek textbooks (Mounce), its workbook, plus the advanced materials that go with it (e.g. Wallace) alongside the Pratico-Van Pelt Hebrew materials. If you're not taking a class (or even if you are), you can buy the video lectures as well, which should get you going.
Now, personally, I find that bundle too expensive and would love to see it broken up, but if you're looking for an all-in-one solution, that's probably the best place to start.
