How many blessings does a person recite when kindling the Chanukah lamp on the first night?
On the first night, three blessings are recited: l'hadlik ner Chanukah, she'asah nissim, and shehecheyanu. On subsequent nights only the first two are said.
Question 2
How many days per year is the complete Hallel recited in Eretz Yisrael, according to the Rambam?
Eighteen days: eight days of Sukkot, eight days of Chanukah, the first day of Pesach, and Shavuot. In the diaspora it is twenty-one.
Question 3
What is the halachic consequence of reciting Hallel out of sequence?
Halacha 9 rules explicitly that a person who reads Hallel in improper sequence does not fulfill his obligation.
Question 4
How many times does the congregation respond 'Halleluyah' throughout the entire Hallel in the ancient call-and-response custom?
Halacha 12 records that the congregation responds Halleluyah 123 times — a mnemonic for the years of Aaron's life.
Question 5
If a minor leads the Hallel recitation, how must adult men fulfill their obligation?
Halacha 14 rules that when the leader is a minor, slave, or woman — none of whom are obligated in Hallel — adults must repeat every single word themselves, since the principle of 'listener as reciter' applies only when the leader is also obligated.
