Remember the Sabbath day, to keep it holy. Six days shalt thou labor,
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.
EXODUS 20:8-11
