Here are the verses with “σαββασ” in it. The word is just part of the whole word so that the search included all the suffixes and prefixes like:
run* will give you run, runs, running, etc.
Finally, I invite you to see for yourself when the exact same word is translated one way versus the other, Sabbath vs. first day of the week.
After the verse I put the KJV translation.
