“death where is your sting?” It says in Corinthians. Here as god elaborates on the priesthood, the sting of death is central.
We are in rebellion, we deserve to die. We are broken. An animal must die every evening and every morning for the Sins of Israel – I think this is just during the conservation of the priests, not sure.
The consecration of the priests segments the animals in a way people understand… the good bits burn deliciously for God to smell, the prime cuts are waved at God. They show love, and that he deserves the best, I suppose. The intestines are taken out of the camp and burned for sin.
It’s a vegetarian nightmare, but it’s supposed to be ghastly, sin is ghastly.
Also, they are herders, animals are to an extent their currency. On a simple level, if they are going to give back to express their understanding of and appreciation for god’s love and forgiveness, it’s going to be animals and grain.
The consecration of the priests is so fandangled. Humans are rarely so engaged in survival that have no energy for spiritual work. We do art, we entertain ourselves, we laugh, we put seemingly pointless effort into stuff that scratches our need for meaning.
God gives them the means of expressing their relationship with God.
