Malachi 1:7

1:7 You are offering improper sacrifices on my altar, yet you ask, ‘How have we offended you?’ By treating the table of the Lord as if it is of no importance!

Malachi 3:2

3:2 Who can endure the day of his coming? Who can keep standing when he appears? For he will be like a refiner’s fire, like a launderer’s soap.
