Caller: "Have you ever heard of the word hallelujah?"
Caller: "Can you look that up for me and give me the definition?"
Me: "Yes, I can do that for you. Hold on please."
I retrieve the Oxford English Dictionary volume six, and read the first definition.
HALLELUJAH: The exclamation of 'Praise (ye) the Lord (Jah or Jehovah)' , which
occurs in many psalms and anthems; hence, a song of praise to God;
Caller: "So what does that mean?"
Me: "It means that the word Hallelujah is used to praise the Lord."
Caller: "Hallelujah, and that's a good thing! Please and thank you."
