Negative Mitzvah 195
It is forbidden to eat or drink more than our needs demand
Leviticus 19:26 "You shall not eat anything with blood"
HaShem provides us with many things to enjoy.
Food is certainly one of the most important things that we enjoy.
From the moment we are born, eating becomes part of our daily lives.
Many of us don't just eat to build our bodies and keep our health!
We often nosh, eating foods just because they taste good.
HaShem wants us to enjoy our food, but not to eat or drink too much.
For example, on Shabbat and Holidays, we often have special cakes and dishes. This adds to the enjoyment of the holiday.
While we all know that food should taste good and we should enjoy what we eat, the Torah warns us that eating or drinking too much is not good for our bodies.
This Negative Mitzvah cautions us not to develop wrong eating habits, by drinking or eating in excess of our needs.
(In the Torah there is a description of what is called a "stubborn and rebellious son" - Ben Sorer U'Moreh.
This description (Deuteronomy 21:18-21) provides us with an account of what exactly is meant by eating and drinking too much.)
Positive Mitzvah 37
Burials in which a Priest must be involved
Leviticus 21:3 "For her, he may become impure"
The Torah regards priests as very holy.
They should not become impure (see Negative Mitzvah 166).
Therefore, they must not come in contact with a dead body (see Positive Mitzvah 107).
Nevertheless, the Torah commanded them to attend the funeral of their closest relatives.
The Torah lists these relatives as follows:
Mother; Father; Son; Daughter; Brother; and unmarried Sister.
