The Institute of Biblical Culture has just launched, and they are registering now for courses beginning in the fall. These live online courses are taught by Jewish and Christian professors on subjects such as biblical literature, biblical archaeology, and biblical backgrounds. You can start here, or go straight to the list of classes being offered this fall.
Here’s one suggestion: you can take a course on Rabbinic Literature, including Mishnah and the Talmud, from a rabbi. The early bird discount ($100 off) ends on Friday.
