The Mosaic Law has ended in Israel/Jerusalem in the 1st century. Including Sabbath.
"For all the prophets and the law until John."
Mt 11:13
"Before the coming of this faith, we were held in custody under the law...
So the law was our guardian until Christ came...
Now that this faith has come, we are no longer under a guardian."
Gal 3:23-25
"So, my brothers, you also died to the law through the body of Christ, that you might belong to another"
R 7:4
"But now, by dying to what once bound us, we have been released from the law so that we serve in the new way
of the Spirit, and not in the old way of the written code."
R 7:6
"For he himself is our peace, who has made the two groups one and has destroyed the barrier, the dividing wall of hostility,
by setting aside in his flesh the law with its commands (ἐντολῶν) and ordinances (δόγμασιν)".
Eph 2:15
Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day.
These are a shadow of the things that were to come; the reality, however, is found in Christ.
Col 2:16
There is plenty about this topic in Galatians and Romans. And in Acts its stated during the Jerusalem council that Gentiles do not need to keep the Mosaic Law.
