16 When they envied Moses in the camp, And Aaron the saint of the LORD,
17 The earth opened up and swallowed Dathan, And covered the faction of Abiram.
18 A fire was kindled in their company; The flame burned up the wicked.
God recognizes the power of envy to destroy His work. It is, of course, possible for a person gripped with envy to repent, and God may well have worked in the hearts of these men before He finally destroyed them. But if that doesn't work, God still has a cure: the destruction of the envious.
If you see someone being blessed by God more than you, you can turn to envy. Or you can ask the person for advice on how to obtain God's blessings.
