We cannot rightly divide the word of truth  if we do not understand that after ancient Israel made the golden calf, they had  two separate laws:  1.  The Ten Commandments.  2.  "The yoke of bondage" that included circumcision, the food laws, the feast days and all the washings and sacrifices of the ceremonial law. The scriptures teach us that “the yoke of bondage” was a temporary law until the resurrection of Christ:

Galatians 3:19 Wherefore then serveth the law? [the yoke of bondage] IT WAS ADDED because of transgressions, TILL THE SEED SHOULD COME to whom the promise was made; and it was ordained by angels in the hand of a mediator.

In the temple service, of the "yoke of bondage", special offerings and sacrifices were required on the sabbath days --the scriptures teach us they were a shadow of things to come ...

Num 28:9  And on the sabbath day two lambs of the first year without spot, and two tenth deals of flour for a meat offering, mingled with oil, and the drink offering thereof:

Those ceremonial services of the sabbath day have been abolished with the entire "yoke of bondage.";  but we must still obey The Sabbath Commandment because it is one of the Ten Commandments.

NOTE:
                     
In addition to the Greek and Latin manuscripts of the New Testament, there is a third text called the Peshitta.   The Peshitta is from ancient Eastern manuscripts written in Aramaic, the natural language of Jesus.  Hebrews 4:9 in the Peshitta text reads:
       
"It is therefore the duty of the people of God  to keep the Sabbath."
