Ezekiel 7

"They will throw their silver into the streets,
And their gold will be like refuse;
Their silver and their gold will not be able to deliver them
In the day of the wrath of the Lord;
They will not satisfy their souls,
Nor fill their stomachs,
Because it became their stumbling block of iniquity." v.19

Read chapter 7
This chapter speaks of the captivity that was soon to take place in Israel when the enemy, the Babylonians, would enter and attack, kill, spoil, etc.  Those who survive are said to have thrown away their silver and gold like refuse.  As they are fleeing from the enemy they can't carry or hold on to these precious metals as it won't save them so they cast them off.  Also, they know that that money is what they used to feed their sin and purchase abominable things and no longer want anything to do with it.  Just as 1 Timothy 6:16 says "for the love of money is the root of all kinds of evil."  Yet not only was silver and gold for money but for what they fashioned in to idols.  They realize they can't buy their salvation, that it will not deliver them in the day of wrath.  
They will not be able to satisfy their cravings and lusts.  Because they were not able to discipline their bodies and it's cravings it therefore caused them to stumble into iniquity, giving in to desire.  ( I.e. Just because I crave chocolate doesn't mean I should just eat it whenever I want or just as one craves sex doesn't mean they can just have sex whenever they want for they will have repercussions in the long run being addicted or dependent to chocolate or sex that is bondage rather than freedom when given in to desire and lust.) 
How have you seen money be an idol to people?  What would be the hardest material item of yours to cast away?  What craving or desire do you have a hard time disciplining or feeling in bondage to?
