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 2:13

2:13 You also do this: You cover the altar of the Lord with tears as you weep and groan, because he no longer pays any attention to the offering nor accepts it favorably from you.
