A. The written Torah is complemented and explained in great length in the Oral Torah (which shares the same source at Sinai). Think of it like opening a folder on a friend’s computer (with permission, of course). Dozens of file names pop up. The file names tell you just a hint of what’s inside the file, and sometimes the names aren’t all that direct. The Written Torah is the folder, with all the file names of Mitzvahs inside. In order to make any sense out of it – you need to open up the Oral file on that. Another way to view it is to think of all the Torah text as hyperlinked. It’s not just the text itself, but what that text opens up into. This verse is an excellent example: Fat and Milk share the exact same Hebrew spelling, the only difference is in pronounciation. If not for an Oral tradition, we would never know from the text – is it the mother’s milk or fat? And fat would have been the more likely interpretation for a cooking ingredient.
