Argument-In Matthew 28:1, the Greek word for "week" is "sabbaton," but it seems to have nothing to do with the weekly Sabbath.

The word “week” in Matthew 28:1 is also derived from the Greek plural word for Sabbath, i.e. “SABBATA.” (Even though the Greek in Matthew 28:1 is “sabbaton,” it is again the genitive plural of “sabbata,” since it says, in the original Greek, “… as it was getting dusk toward the first day OF the week…”). Young’s Analytical Concordance of the Bible explains that the phrase “week” in Matthew 28:1 is to be understood as “from Sabbath to Sabbath”–that is, a week is composed of the time from one weekly Sabbath to the next weekly Sabbath. It is mostly used in the plural (“sabbata”), meaning “one OF Sabbaths,” signifying the first day AFTER the weekly Sabbath. Examples where the word “week” is translated from the Greek plural word for Sabbath (i.e., “sabbata”), can be found, in addition to Matthew 28:1, in Mark 16:2; Luke 24:1; John 20:1, 19; Acts 20:7; and 1 Corinthians 16:2.

In a few cases, such as Luke 18:12 and Mark 16:9, the Greek word for “week” is in the singular form for Sabbath (i.e., “sabbaton”). In Luke 18:12, the Pharisee claims that he is fasting “twice a week.” It literally says: “twice of the Sabbath”; that is, “twice in the days after the weekly Sabbath.”

Rather than abolishing the weekly and annual Sabbaths, the above-quoted examples show that the New Testament clearly upholds the sanctity of God’s weekly and annual Holy Days.
