Ezekiel 7:19 & 20

"'"They will throw their silver into the streets, and their gold will be treated as a thing unclean. Their silver and gold will not be able to deliver them in the day of the Lord's wrath. It will not satisfy their hunger or fill  their stomachs, for it has caused them to stumble into sin. They took pride in their beautiful jewelry and used it to make their detestable idols. They made it into vile images; therefore I will make it a thing unclean for them."'" NIV translation

The people had been blessed with material possessions by God. They had used that gold and silver to make idols but, in the last day, the wealth will mean nothing. Ezekiel shares a quote from Isaiah 2 in describing how the people will discard the wealth. This also reminds us of the description of the last days that is contained in Revelation. There we see that wealth does not matter if you do not have the mark of the beast.

Ezekiel 7:21 & 22

"'I will give their wealth as plunder to foreigners and as loot to the wicked of the earth, who will defile it. I will turn my face away from the people, and robbers will desecrate the place I treasure. They will enter it and will defile it.'" NIV translation

This passage speaks of the final fall of Jerusalem as described in Zechariah 14. Jesus will hand the city over to the nations for a short time before He judges them and establishes His kingdom.
