Your referencing modern Greek meanings not Koine Greek meanings of κυριακή ημέρα (the Lord's day).
No I'm not. I have only referenced the original koine Greek.
If you believe that the Koine Greek of κυριακή ημέρα means Sunday you should be able to provide a single biblical Koine Greek dictionary that says κυριακή ημέρα means Sunday. Where is it? You have none do you.
No problem. Here you go....
