I just visited Yahoo Answers Religion/Spirituality section, and just have to respond to something I read there. I’m putting a response here because others might have similar questions. One of the posters made a comment about Leviticus 14 and “bird blood” cleansing a house. Clearly, he didn’t agree with the concept.
There were several OT sacrifices which involved the use of birds, sometimes because that’s all the offerer could afford, sometimes not. In the case of Leviticus 14, there are at least two things to keep in mind.
First, it was a health issue. The Israelites didn’t have the technology to discover whether any particular mold was toxic. It’s better to be safe than sorry, so every mold was treated as toxic. They didn’t have bleach – I don’t think Clorox was around back then – so the procedure prescribed was the next best thing: scrape away the infected material and replaster, then, if the mold came back, the house had to be destroyed. Houses weren’t as complicated then as they are now, so rebuilding a house wouldn’t be so difficult.
Second, there was a moral component. The house was considered “polluted.” Even those who entered the house were considered polluted and had to go through ceremonial cleansing. The sacrifice of a bird was to demonstrate that the house was “clean,” Leviticus 14:48-53: the procedure had worked. Hebrews 10:4 (NKJV) says “it is not possible that the blood of bulls and goats [and birds] could take away sin.” All the Old Testament sacrifices were merely symbolic of the sacrifice of the Lord Jesus; they pointed forward to His death on Calvary. It wasn’t just sacrifice for the sake of shedding blood. It was to teach the people by picture and symbol the necessity of cleansing from pollution, whether for health, as in the case of Leviticus 14, or personally, because they were all sinners. So are we.
There are no more sacrifices for sin. The Lord Jesus died once for sin. The Old Testament sacrifices were thousands of fingers pointing toward Him.
