A wound caused by the hot springs of Tiberias is classified as:
Halacha 2 explicitly states that a wound from the hot springs of Tiberias, olive dregs, or similar is classified as a sh'chin (boil), not a michveh (burn), since it is not directly from fire.
Question 2
When a boil is in the festering (mordin) stage, how is it treated with respect to tzara'at?
Halacha 3 states that as long as boils and burns are fresh and festering (mordin), they do not impart tzara'at impurity at all.
Question 3
A baheret appears on the scab (tzeret) of a healing boil. How many signs apply, and what is the maximum isolation period?
Halacha 4 states that the scabbing stage (tzeret ha-sh'chin) has only two signs — white hair and spreading — and requires isolation of only one week, not two.
Question 4
A blemish spans both a boil and an adjacent burn. What is the ruling?
Halacha 5 states explicitly: if there is a boil next to a burn and a baheret of a gris extends over both, the person is pure. Boil and burn cannot combine — the Torah separated them specifically to teach this.
Question 5
A person who loses all hair on the back of their head (keireiach) — how many signs apply to a blemish on that area?
Halacha 9 states that karachet and gabachet contract impurity through two signs only — michyah and spreading. White hair does not apply since these areas have no hair. The verse states they follow the law of 'the appearance of tzara'at on the skin.'
