Yahve asked Abraham to give it him material riches, like gold, silver, and animal sacrifices instead of human sacrifices like the other deities or their surroundings, this is the start of their obsession with riches as the one with more riches will be the more able to get a bless.
And for the red cow is just the animal they used to sacrifice on their temple, the Levi (priest from the family of Moses' brother Aaron) got a nice barbeque, people were happy socializing in the temple during the sabbath after a nice bath in the nearest pool (Mikveh) and that's it.
