Genesis 2:1-3
Thus the heavens and the earth, and all the host of them, were finished. And on the seventh day God ended His work which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.

Exodus 35:2
"Work shall be done for six days, but the seventh day shall be a holy day for you, a Sabbath of rest to the LORD. Whoever does any work on it shall be put to death.

Leviticus 23:3
'Six days shall work be done, but the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work on it; it is the Sabbath of the LORD in all your dwellings.

Isaiah 58:13-14
"If you turn away your foot from the Sabbath, From doing your pleasure on My holy day, And call the Sabbath a delight, The holy day of the LORD honorable, And shall honor Him, not doing your own ways, Nor finding your own pleasure, Nor speaking your own words, Then you shall delight yourself in the LORD; And I will cause you to ride on the high hills of the earth, And feed you with the heritage of Jacob your father. The mouth of the LORD has spoken."

Matthew 12:1-8
At that time Jesus went through the grainfields on the Sabbath. And His disciples were hungry, and began to pluck heads of grain and to eat. But when the Pharises saw it, they said to Him, "Look, Your disciples are doing what is not lawful to do on the Sabbath!" Then He said to them, "Have you not read what David did when he was hungry, he and those who were with him: "how he entered the house of God and ate the showbread which was not lawful for him to eat, nor for those who were with him, but only for the priests? "Or have you not read in the law that on the Sabbath the priests in the temple profane the Sabbath, and are blameless? "But I say to you that in this place there is One greater than the temple. "But if you had known what this means, 'I desire mercy and not sacrifice,' you would not have condemned the guiltless. "For the Son of Man is Lord even of the Sabbath."

Matthew 12:10-13
And behold, there was a man who had a withered hand. And they asked Him, saying, "Is it lawful to heal on the Sabbath?"-that they might accuse Him. Then He said to them, "What man is there among you who has one sheep, and if it falls into a pit on the Sabbath, will not lay hold of it and lift it out? "Of how much more value then is a man than a sheep? Therefore it is lawful to do good on the Sabbath." Then He said to the man, "Stretch out your hand." And he stretched it out, and it was restored as whole as the other.
