Malachi 1:6
The Sacrilege of Priestly Service
1:6 “A son naturally honors his father and a slave respects his master. If I am your father, where is my honor? If I am your master, where is my respect? The Lord who rules over all asks you this, you priests who make light of my name! But you reply, ‘How have we made light of your name?’
Malachi 3:10
3:10 “Bring the entire tithe into the storehouse so that there may be food in my temple. Test me in this matter,” says the Lord who rules over all, “to see if I will not open for you the windows of heaven and pour out for you a blessing until there is no room for it all.
