Leviticus 16

Wow, today's reading covers the most interesting of the ritual regulations so far in Leviticus (at least to me). Most unique here is the presentation of two goats: one for an offering to the Lord, the other to be set free in the wilderness. On the face of it that isn't too amazing, but the mysteriousness surrounding why that is done and the wording used to describe are very strange: "He must then take the two goats and stand them before the Lord at the entrance of the Meeting Tent, 16:8 and Aaron is to cast lots over the two goats, one lot for the Lord and one lot for Azazel." (v 14-15, NET)

I could go into more depth here, but not being an expert on the subject the best I could do would be paraphrasing the work of others - so I would just recommend reading verses 3-10 and 20-22, and then consulting a good study Bible or other resource. The notes on the NET Bible for that section are worth reading, and give further direction if you want to go deeper.
