There are so many traditions in any religion. Our friend came to our house for the first time on Saturday. He brought a bottle of wine and 18 pennies. The word for life in Israel is chai which is equal to 8 and 10 that makes up 18. That is why in the Jewish religion, people give gifts in multiples of 18. It is a way of celebrating a good thing.
I really liked the simplicity and meaning of the gift. Made me feel guilty about not hanging the mezuzahs yet. I plan on doing it when we get home. In need of a few nails.
