You're trying to justify human blood atonement and that's not how it works at all.
WHAT IS KOSHER MEAT? DEVOID OF BLOOD. NO BLOOD OR FAT ON ALTAR. BLOOD IS FORBIDDEN FOR CONSUMPTION.
Just so we’re perfectly clear here...
The only sin offering is confession and repentance. There’s no blood involved. Turn away from your transgressions and LIVE. Your sin shouldn’t be a stumbling block.
You’re trying to reference ritual purity laws, which AGAIN has to be a kosher slaughter with no blood or fat. It’s not the same thing.
Barley must be really confusing.
