In the 4th Commandment (Exodus 20:8-11), God
tells us to 'remember
the sabbath day, to keep it holy. Six days
shalt thou labour, and do all
thy work: But the seventh day is the sabbath
of the LORD thy God: in
it thou shalt not do any work, thou, nor thy
son, nor thy daughter, thy
manservant, nor thy maidservant, nor thy cattle,
nor thy stranger that
is within thy gates: For in six days the LORD
made heaven and earth,
the sea, and all that in them is, and rested
the seventh day: wherefore
the LORD blessed the sabbath day, and hallowed
it.
