He was saying man was redeemed with His death. Man’s iron clad no way out death was ended there. “It is finished.”
He was not saying all laws ceased. Ceremonial sacrificial laws pointing to a sacrificial lamb were no longer needed.
There may have and probably were many laws that pertained to the Children of Israel due to their 40 year trek through the wilderness, concerning things from hygiene and social mores relating to the groups exposure to the ill effects of some personal activity.
Name one other thing out of the Ten Commandments that we are not to observe now? If the nine are to be observed, why not the one dealing with the Sabbath?
Jesus died and was buried before sundown on Friday. He arose after the Sabbath was over.
Seems to me He made it pretty clear the fourth commandment Sabbath was still an important commandment.
At no time are we specifically told never to follow the Ten Commandments, particularly the fourth pursuant to this discussion.
And again, the Ten Commandments are only part of the complete commandments of G-d.
The first line of the Ten Commandments is a statement: "I Am the Lord Thy G-d" which is a statement then follows Thou shalt not etc, etc.
