It wasn't a blind spot, Paul was quoting the second greatest commandments that came from the Ten Commandments of love towards our neighbor, why the first 4 commandments was absent, not just the Sabbath commandment. He also said if there are "any other commandments" are there other commandments that God wrote and God spoke from this unit, of course.
The greatest commandments love to God with all our heart are from this same unit just as Jesus said Deut6:5
Exo 20:1 And God spoke all these words, saying:
2 “I
am the Lord your God, who brought you out of the land of Egypt, out of the house of [
a]bondage.
3 “You shall have no other gods before Me.
4 “You shall not make for yourself a carved image—any likeness
of anything that
is in heaven above, or that
is in the earth beneath, or that
is in the water under the earth;
5 you shall not bow down to them nor [
b]serve them. For I, the Lord your God,
am a jealous God, visiting[
c] the iniquity of the fathers upon the children to the third and fourth
generations of those who hate Me,
6 but showing mercy to thousands, to those who love Me and keep My commandments.
7 “You shall not take the name of the Lord your God in vain, for the Lord will not hold
him guiltless who takes His name in vain.
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.
Heb. 7:11-10:1 - this covers a lot and Heb7:11 without the next verses that shows the context of what is being changed shows me how Scripture is being interpreted, sadly taken out of context.
Jesus in His own Words said the commandments of God would not end Mat5:17-30, not a jot or tittle I am sticking with what He said Mat4:4 He warned us about laying aside this very thing and could not condemn this teaching more Mat15:3-14 Mark7:7-13
