Negative Mitzvah 266
It is forbidden to envy other people's possessions
Deuteronomy 5:18 "You shall not desire your neighbor's house"
We are commanded not to be jealous or envious of other people's belongings.
The word "house" includes all that which belongs to another person.
The difference between the previous Negative Mitzvah (265) and this Negative Mitzvah is that, this Negative Mitzvah forbids us to be jealous or envious of something that belongs to another person.
The previous Negative Mitzvah forbids us to try to purchase or gain an object that we desire which belongs to another person.
