hallowed be thy name
In ancient time the ”name” did not just mean the person who carried it, but the person who ”stood behind” it. Name and person were in unity. Thus, the Greek word we encounter here, ”onoma”, not only meant ”name”, but above all, ”title, person, authority, power”. In judicial vocabulary the comprehensive meaning comes through in ”power of attorney”, or ”Proxy”; someone is acting with authority on behalf of someone else.
Father, you alone are pure and almighty!
As Christians when we express such words we call it ”worship”, which means to pay great honor and respect.
