I was following you but it’s not the same comparison because God did claim His day very clearly by the scriptures shown in my initial response to you. I’ll post them again to make it easier, so you do not need to search for them.
Exodus 20: 8 “Remember the Sabbath day, to keep it holy. 9 Six days you shall labor and do all your work, 10
but the seventh day is the Sabbath of the Lord your God.
In it you shall do no work: you, nor your son, nor your daughter, nor your male servant, nor your female servant, nor your cattle, nor your stranger who
is within your gates. 11 For
in six days the Lord made the heavens and the earth, the sea, and all that
is in them, and rested
the seventh day.Therefore the Lord blessed the Sabbath day and hallowed it.
Isaiah 58:13 “If you turn away your foot from the Sabbath,
From doing your pleasure on
My holy day, And call
the Sabbath a delight
The holy day of the Lord honorable, And shall honor Him, not doing your own ways,
Nor finding your own pleasure, Nor speaking
your own words, (how can you possibly argue the Lord's day is the first day when this makes it so clear which is the Lords day)
Mark 2:28 28 Therefore the Son of Man is also
Lord of the Sabbath.”
There is no scripture telling us Sunday is the Lords day or God’s new holy day. Which is why the Sabbath will continue for eternity to be God’s chosen day and not the first day.
Isaiah 66:23
