It is easy for a modern audience to look to the text of the Torah and point out how simple or backward it is according to our modern and enlightened view of the world. This passage in Leviticus is a minefield of gotchas for this type of criticism. However, when we understand what topics it is that the Bible is addressing, rather than pushing our own agenda onto the text, we might find that what is being described is, in fact, quite profound as it teaches us about God and those who are to come into His presence.
