Seven Day Cleansing Process
Parasha CHUKAT NUMBERS 19:11-12
The person who touches a corpse is unclean for 7 days.
Therefore, cleansing on the 7th day makes sense to me.
Do the days represent the number of days after touching the corpse or the days of the week (3rd day would be Tuesday, 7th day would be Saturday)?
Main Question: What is the significance of the third day?
