Do not testify false witness against your neighbor. (in certain circumstances)
I look at is lying in court and/or lying that causes serious problems for the target of the lies so I can kind of accept that one as reasonable. Not something we cannot figure out for ourselves however.
My argument with graven images is that maybe one should actually try a religious argument to see how Christians try to argue out of it. One It have heard is that is not how it should be interpreted without giving any reasonable alternate.
Graven images is an interesting one.
I once heard some scholar argue that the correct translation from Torah would simply be "images" (no mention of graven).
He made the argument that this was for the Hebrews to separate themselves from the other civilizations that were using hieroglyphs and picture writing. I think his reasoning is a bit of a stretch, but he went on to mention the Hebrews strong focus on literacy, and how it was a source of strength--and how in the Beginning was the word.
The commandment is probably better explained as a rejection of ancient Sumarian practices though.
