Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work:
John 6:27
Labour not for the meat which perisheth, but for that meat which endureth unto everlasting life, which the Son of man shall give unto you: for him hath God the Father sealed.
1 Peter 1:15
But as he which hath called you is holy, so be ye holy in all manner of conversation;
1 Peter 1:16
Because it is written, Be ye holy; for I am holy.
[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 (KJV)
But the seventh day
I am under the influence that we are required to to be holy 7 days a week.
