Malachi
Don't sacrifice defective animals (1-6)
2 God will spread dung on your face (If you don't give him glory) (1-17)
3 I'll send my messenger (1-4)
You have robbed me (by not paying your tithes) (5-18)
The day cometh, that shall burn as an oven; and all the proud, yea, and all that do wickedly, shall be stubble: and the day that cometh shall burn them up. 4:1
