Daily Aliya for Metzora, Shlishi (3rd Aliya)
Aliya Summary: If the individual suffering from tzara’at cannot afford the above sacrifices, two birds can be substituted for two of the animals. This Aliya describes the slightly different purification process reserved for the impoverished person.
The significance of placing the blood on the big toe and thumb of the person might be because if the person did anything wrong, the thumb was likely instrumental in anything their hands did, and the big toe was instrumental in anywhere the person went. The blood would then remind the person to use the body we were given to do good things, not otherwise.
