In response to the comment By Elaine: So, when Cain and Able brought their sacrifices to the Lord, was Able to kill the lamb/lambs? What is the interpretation of that passage?
In my opinion Abel's offering was most likely a dairy product.
And her comment: The scripture says that there is no remission of sins without the shedding of blood.
My personal interpretation of this passage I expressed in an article is:
“9:22 And almost all things, according to the law, are cleansed with blood, and apart from the effusion of blood is not remission.
The pouring out of blood, aimatekcusias in this passage, most likely
refers to the blood pourings, aima ekceei, of Leviticus 4 LXX. There this
ritual at every point is never apart from attempting to forgiving sins. So
the ritual points to the need for the true forgiveness of Christ . It's also
possible that while the first part of this verse refers to the blood rituals
of the Old Testament, the second half refers to the blood of Christ being
the sole cause of all forgiveness.“
