Introduction to Mitzvot 330-359:

Laws of Forbidden Marriages and Relations

A wedding is a very happy and joyous occasion.

Before singing and dancing with the bride and groom, we gather together for the special ceremony - the "Chuppah".

Have you ever had the chance to get close enough to see what takes place under that velvet canopy where the bride and groom stand?

In that joyful, yet serious ceremony, the groom puts a ring on his bride's finger and says: Harei At Mekudeshet Li Kedat Moshe V'Yisrael."

When the groom says this he is telling his bride that she is now his wife. He uses the word "Mekudeshet" - showing that "Kedushah," holiness, is the most important part of a Jewish marriage.

The following Mitzvot are examples of forbidden marriages that can never be considered holy according to Torah law.

Leviticus 18:11 "She is the daughter of your father and your father's wife...do not act immodestly with her"

It is forbidden to take your half-sister as a wife.

Negative Mitzvah 334: Prohibition against marriage with one's son's daughter

It is forbidden to take your son's daughter as a wife (Your granddaughter born to your son and his wife).

Just as you search out a material career, so you must also search out a spiritual one. But there is a difference: With a material career you can only plow and sow and await the rains. With your spiritual career you must provide the rain as well -- in other words it is up to you to fill it with life.
