"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:"
- Exodus 20:8-10

"Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching."
- Hebrews 10:25
