Exodus 20:8-12
8 Remember the sabbath day, and keep it holy. 9For six days you shall labour and do all your work. 10But the seventh day is a sabbath to the Lord your God; you shall not do any work—you, your son or your daughter, your male or female slave, your livestock, or the alien resident in your towns. 11For in six days the Lord made heaven and earth, the sea, and all that is in them, but rested the seventh day; therefore the Lord blessed the sabbath day and consecrated it.
12 Honour your father and your mother, so that your days may be long in the land that the Lord your God is giving you.
Mark 2:23-28
Pronouncement about the Sabbath
23 One sabbath he was going through the cornfields; and as they made their way his disciples began to pluck heads of grain. 24The Pharisees said to him, ‘Look, why are they doing what is not lawful on the sabbath?’ 25And he said to them, ‘Have you never read what David did when he and his companions were hungry and in need of food? 26He entered the house of God, when Abiathar was high priest, and ate the bread of the Presence, which it is not lawful for any but the priests to eat, and he gave some to his companions.’ 27Then he said to them, ‘The sabbath was made for humankind, and not humankind for the sabbath; 28so the Son of Man is lord even of the sabbath.’
