Who is your neighbor in the Ten Commandments?

Answer 1

When originally written, the word "neighbor" (or "your fellow") is used to mean any other Israelite. It would be acceptable to covet a foreigner's goods, or his wife, but not those of another Israelite.

The word generally translated here as 'neighbor' is now taken to mean any other person, regardless of religion or ethnicity.

Answer 2

The word is a mistranslation; the Hebrew actually means "your fellow." The Ten Commandments (with the exception of the Sabbath) apply equally to people of all religions; and nor are Israelites permitted to covet or take the wife or goods of anyone (Code of Jewish Law, Choshen Mishpat 359). This is an original tradition and has never changed.
