Warning From James to the Rich

1 Come now, you rich, weep and howl for the miseries that are coming upon you.2 Your riches have rotted and your garments are moth-eaten.3 Your gold and silver have corroded, and their corrosion will be evidence against you and will eat your flesh like fire. You have laid up treasure in the last days.4 Behold, the wages of the laborers who mowed your fields, which you kept back by fraud, are crying out against you, and the cries of the harvesters have reached the ears of the Lord of hosts.5 You have lived on the earth in luxury and in self-indulgence. You have fattened your hearts in a day of slaughter.6 You have condemned and murdered the righteous person. He does not resist you.

-- James 5:1-6 ESV

This is a grave warning to those who have violated Yeshua's warning to store up your treasure in heaven where moth and rust do not destroy.  James is specifically warning people who hoard their wealth instead of giving it freely. The work of the church is limited by greed -- ultimately it is the fatherless and the widow that suffer most from this greed.

19 "Do not lay up for yourselves treasures on earth, where moth and rustt destroy and where thieves break in and steal,20 but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal.21 For where your treasure is, there your heart will be also.
-- Matthew 6:19-21 ESV
