Question
Dear Rabbi,
What was Korban Omer?
Whats the connection of 2nd day of Omer to Yashan?
What is Yashan?[I read the definition but I dont know if I understood it]
Thank you for helping me learn Torah
Answer
Shalom,
Regarding the first questions see here: https://ph.yhb.org.il/en/05-02-01/
Regarding "yashan" – that means grain that has taken root before the 16th of Nisan. Otherwise it is called "chadash" and is forbidden to eat until the korban omer is performed.
All the best!
