When the blood was brought by the priest, if it was unsatisfactory, or the priest was unworthy, what happened?Satisfaction does not adequately describe what happened. If you go back and read in Leviticus the details of the sacrifices, including the lamb, the bullock, and especially the goat that is led away into the wilderness and you will see that a transferring of sin, substitution, was occurring.
None of the other matters, if the blood were not the satisfaction.
The rest speak not of substitution, but of transferring and victory.
"Wilderness" is an unfortunate translation. The scapegoat was lead outside the camp to a field and turned loose, never to be used again.
When our Lord died, outside the city walls (whether He had to climb a hill or was placed at the bottom along the roadway has long been discussed it is all the place of Golgotha) the blood was shed, the death and burial were to take place. Again, it is a place of victory, not substitution. A place of satisfaction, not substitution.
