Riddles and Trivia

1. The words זאֹת הַתּוֹרָה appear three times in the entire Torah. This week’s parsha has one instance of it.

2. Mr. Feinberg is a good father. He teaches his children well how to perform mitzvos so that they’ll be ready to do them when they reach Bar / Bat Mitzva. Today – on a beautiful day in the month of Nissan, Mr. Feinberg’s friends overheard him saying to his son Moishy: “Moishy - I am doing this mitzvah today, and you should not. But, when you’ll reach Bar Mitzva, you will do it on this day, and I will not.”
