Actually it not only says your neighbor's wife, but everything that belongs to your neighbor. Have you ever told a lie? Have you ever took anything that belonged to someone else? Have you always honored your parents? The thing is, if you break one rule you are as guilty as if you had broken them all.<quoted text>
What's so difficult about following the 10 Commandments?
Well, maybe thou shalt not covet thy neighbor's wife may be difficult for a lot of people, but the rest seem pretty easy to me.
James 2: 10 For whoever keeps the whole law and yet stumbles in one point,he has become guilty of all. 11 For He who said,“DO NOT COMMIT ADULTERY,” also said,“DO NOT COMMIT MURDER.” Now if you do not commit adultery, but do commit murder, you have become a transgressor of the law.
