Why is a value placed only on the unclean animals in Leviticus 27:11-12?

Answer From The Annual Reading Schedule - Week 30 Notes For Leviticus: It tells you right in verse 11 the answer – it is because an unclean animal is an animal of which they do not bring an offering to Yahweh. In other words, the animal being vowed to be given would be offered on the altar to Yahweh. However, we cannot offer an unclean animal to Yahweh. That would be an abomination to sacrifice and offer an unclean animal to Yahweh. So instead, if a vow is made for an unclean animal, it is not sacrificed and offered as an offering but instead is valued at a price and that value is paid to the priest. This should show us also that Yahweh does not want or accept a dead unclean animal in His Set-Apart place, and therefore, neither does He want dead unclean animals in our bodies either. After all, our bodies are the dwelling place of the Set-Apart Spirit (1 Corinthians 3:16, 6:19-20).
