The many times that the "Sabbath" of the LORD is given in the New Testament:
Matthew 12:1,2,5,8,10,11,12, 24:20, 28:1;
Mark 1:21, 2:23,24,27,28, 3:2,4, 6:2, 7:6-9, 15:42, 16:1;

John 5:9,10,16,18, 7:22,23, 9:14,16, 12:1 (calculated), 19:31;
Acts 1:2, 13:14,27,42,44, 15:21, 16:13, 17:2, 18:4;
Additional references are:
John 12:1 (six days before the Passover, Jesus was at Lazarus' house, on Sabbath)
Hebrews 3:11, 4:1,3,4,5,8,9,10,11; [Hebrews 4:9 "rest" Greek: sabbatismos, literal sabbath-keeping]
This has been posted previously
Hebrews 3-4 is clear.
Hebrews 4:3,
"my (God's) rest" and
"the works were finished from the foundation of the world", which is a direct reference to
Genesis 2:1-3. It even uses the word
"finished". God rested the 7th day in
Genesis 2:1-3. It is His rest, the 7th day, the sabbath (rest) of the LORD thy God,
Exodus 20:8-11.
Hebrews 4:4,
"he spake in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works", which
"certain place" is
Genesis 2:1-3; re-cited in
Exodus 20:8-11. The 7th day the sabbath (rest) of the LORD thy God.
Hebrews 4:5,
"my (God's) rest)", citing
Psalms 95, which is citing
Genesis 2:1-3;
Exodus 20:8-11, etc. Again, this is the 7th day the sabbath (rest) of God at Creation in
Genesis 2:1-3.
Hebrews 4:6,
"remaineth", from when?
"from the foundation of the world" as per
Hebrews 4:3 and thus it is not new, but has been around from the beginning.
Hebrews 4:9,
"rest", sabbatismos, literally and truly sabbath keeping in scripture and in all known extant Greek sources, dictionaries, and so on and again
"remaineth".
Hebrews 4:10,
"his (God's) rest", which is the 7th day the sabbath (rest) of the LORD thy God from
Genesis 2:1-3., "as God did from his (works)", which "
works were finished from the foundation of the world" as per
Hebrews 4:3.
Hebrews 4:11,
"that rest" (ie God's rest), the 7th day the sabbath (rest) of the LORD thy God.
Look around by using the "search" option on
Hebrews 3-4, and there is found even a whole thread on
Hebrews 3 - 4 that seems to have been around awhile now that has gone into this in some considerable depth-
Hebrews 3-4 [KJB], the 7th Day the Sabbath of the LORD JEHOVAH - "my rest" "remaineth" to My people.
Revelation 1:10 [kuriake hemera, "the Lord's Day" [the 7th Day Sabbath, not "the Day of the Lord", this is totally different in the Greek], see Genesis 2:1-3, Exodus 20:8-11, Deuteronomy 5:12:15, Isaiah 58:13, 66:23, Matthew 12:8, Mark 2:27,28; Luke 6:5 ],
Revelation 10:6 [see also Exodus 20:11, 31:17; Nehemiah 9:6; Psalms 146:6; Acts 4:24, 14:15, Revelation 14:7];
Revelation 14:7 [see previous], etc
Additionally, further references in the Greek are [every single 'first [day] of the week' text, as each text clearly shows that the first day is simply a number, with no special association or designation, other than it is simply one day toward the culmination of the week, being the 7th Day the Sabbath of the LORD thy God]:
Matthew 28:1(a) - (Koine Greek) οψε δε σαββατων (Transliterated) oye de sabbatwn
Matthew 28:1(b) - (Koine Greek) εις μιαν σαββατων (Transliterated) eiV mian sabbatwn
Mark 16:2 - (Koine Greek) και λιαν πρωι της μιας σαββατων (Transliterated) kai lian prwi ths mias sabbatwn
Mark 16:9 - (Koine Greek) αναστας δε πρωι πρωτη σαββατου (Transliterated) anastas de prwi prwth sabbatou
Luke 24:1 - (Koine Greek) τη δε μια των σαββατων (Transliterated) th de mia twn sabbatwn
John 20:1 - (Koine Greek) τη δε μια των σαββατων (Transliterated) th de mia twn sabbatwn
John 20:19 - (Koine Greek) τη μια των σαββατων (Transliterated) th mia twn sabbatwn
Acts 20:7 - (Koine Greek) εν δε τη μια των σαββατων (Transliterated) en de th mia twn sabbatwn
1 Corinthians 16:2 - (Koine Greek) κατα μιαν σαββατων (Transliterated) kata mian sabbatwn
That the Sabbath [of the Lord thy God], [being] the 7th day, is always the culmination of the week in God's Created order and is always referred to as such in all of scripture.
Therefore, every single “first [day] of the week” text upholds the 7th Day Sabbath, and is undeniable evidence of its continued existence and prominence.
