Zevahim 4: Sources of Blood

[Apologies for this late release. Unfortunately, we are beholden to the app we use for publication of each episode, and we were delayed, apparently, by the app updating, or not updating, as the case was. We hope it will be in good form now for a long time to come.]What is the biblical source that the 4 different "blood" acts of worship - slaughter, receiving the blood in a consecrated vessel, bringing the blood to the altar, and throwing the blood on the altar - need to be done specifically for the sake of the specific offering being brought and also for the correct owner of that offering? Also, once those sources are established, a review of how the laws were actually derived from them - with principles of generalizations and specifics being applied.
