What does the Bible verse in Matthew chapter 7 verse 12 mean?

Mt:7:12: Therefore all things whatsoever ye would that men should do to you, do ye even so to them: for this is the law and the prophets.

It means to do unto others as you would have them do unto you. Meaning, if you don't want people to steal from you,do not steal from them;if you do not want people to lie to you,do not lie to them;and if you do not want people to have adultery with your wife/or husband, do not have adultery with others wives/or husbands.
