The Jewish people had other types of ceremonial sabbaths besides the regular weekly Seventh Day Sabbath. You can read more about these in Leviticus. They even had Sabbath years (Leviticus 25). These types, or shadows, along with the burnt offerings and sacrifices described in the Mosaic law all pointed to the plan of redemption. This system was no longer necessary once Jesus died on the cross. These were not in the Ten Commandments. The weekly Sabbath, however, is.
God provides a special blessing for those that keep His Seventh Day Sabbath:
If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words:
Then shalt thou delight thyself in the LORD; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the LORD hath spoken it.
Isaiah 58:13
We will still be keeping the Sabbath in eternity, after the new heavens and the new earth are created:
For as the new heavens and the new earth, which I will make, shall remain before me, saith the LORD, so shall your seed and your name remain.
Isaiah 66:22,23
And it shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the LORD.
