Leviticus 12-14

God instructed Moses about unclean conditions. It took paragraphs to explain all of the situations to teach all of his object lessons about holiness. But the meaning behind the picture of cleansing in 14:5-7 escapes me.  The combination of water, blood, cedarwood, scarlet yarn, hyssop, and a live birds is very specific. Possibly they are representative of Jesus' sacrifical death; the blood and "water" issued from his body, he was nailed to a cedar-like tree, our scarlet sins were nailed there with him, and he was offered a drink with a hyssop branch. The live bird that flew away could be a picture of his resurrection. It was through all of these things that God brings about our cleansing.
It took me about 20 minutes of read time to finish this passage.
