Remember to keep the sabbath day holy (Exodus 20.8)

Remember to keep holy the sabbath day. Six days you may labor and do all your work, but the seventh day is the sabbath of the Lord, your God. (Exodus 20.8-10)

So God blessed the seventh day and made it holy, because on it he rested from all the work he had done in creation.
(Genesis 2.3)

All who keep the sabbath free from profanation and hold to my covenant, them I will bring to my holy mountain and make joyful in my house of prayer; their holocausts and sacrifices will be acceptable on my altar, for my house shall be called a house of prayer for all peoples.
(Isaiah 56.6b-7)

If you hold back your foot on the sabbath from following your own pursuits on my holy day; if you call the sabbath a delight, and the Lord's holy day honorable; If you honor it by not following your ways, seeking your own interests, or speaking with malice-- then you shall delight in the Lord.
(Isaiah 58.13-14a)

He came to Nazareth, where he had grown up, and went according to His custom into the synagogue on the sabbath day.
(Luke 4.16)

When the sabbath came He began to teach in the synagogue, and many who heard Him were astonished. They said, "Where did this man get all this? What kind of wisdom has been given Him? What mighty deeds are wrought by His hands!"
(Mark 6.2)

Then He said to them, "The sabbath was made for man, not man for the sabbath. That is why the Son of Man is lord even of the sabbath."
(Mark 2.27-28)

After the sabbath, as the first day of the week was dawning, Mary Magdalene and the other Mary came to see the tomb…Then the angel said to the women in reply, "Do not be afraid! I know that you are seeking Jesus the crucified. He is not here, for He has been raised just as He said. Come and see the place where He lay."
(Matthew 28.1,5,6)

Therefore, a sabbath rest still remains for the people of God. And whoever enters into God's rest, rests from his own works as God did from his. Therefore, let us strive to enter into that rest, so that no one may fall after the same example of disobedience.
(Hebrews 4.9-11)
