No body changed the Sabbath.
It’s still there as observed by Jews.
It wasn’t given to Gentiles, ever. In fact, since the old Covenant was removed and the new Covenant was established, it’s not used. Or valid.
Jeremiah told everyone it would happen, and the author of Hebrews clearly confirmed that it happened. Along with the Apostles, the Elders of the Church in Jerusalem, etc.

In a nutshell, God changed the Covenant, as He was and is able to.

So G-d breached the eternal covenant?

LOL, no.

That is some real heavy duty indoctrination there. The Sabbath was started at creation (hint no Jews yet), given again at Mt. Sinai (Moses was Hebrew), followed throughout the Bible as permanent and a sign of Gods people and God (you want to be one of Gods people don't you?). Rev. 14:12 It will be kept in Heaven by those who kept the faith and His Commandments.
Not much room for those who did NOT keep Gods Commandments. His House, His Rules.
