Other commandments (though shalt not covet, etc) are concerned with materialism and greed. "Though Shalt Have No Other Gods Before Me" is pretty clearly about precisely what it says on the tin.
"Their end is destruction, their god is their belly, and they glory in their shame, with minds set on earthly things."
- Philippians 3:19
“You cannot slave for God and for Riches”
Riches is capitalized because it’s being personified as a competing god.
To see if that point is actually in the sources, you would need to go into Greek, or look for a good historic analysis of Gospel of Matthews.
[edit]
Ten commandments come from oral tradition, but most probably were written down at least a few hundreds years earlier (500 or 600BC)
And so intellectually insulting, that it's probably responsible for a non-trivial slice of that 50% drop in church attendance.
Luke 14:26:
> If anyone comes to me and does not hate father and mother, wife and children, brothers and sisters--yes, even their own life--such a person cannot be my disciple.

This is hyperbole, which Jesus uses relatively often. It is also more subtle in the original Greek: while we often use the word "hate", the original has more of a connotation of (IIRC) separate-yourself-from. See also:

It is not that one's parents, spouse, siblings are bad in themselves, but that one has to be mindful that the source of being tempted to not act morally and doing the right thing can come from anywhere—even people that we would otherwise cherish.
