'Keep It Holy' in the Bible

And this day shall be unto you a remembrance, and ye shall keep it holy unto the LORD: even throughout your generations after you shall ye keep it holy day, that it be a custom forever.

Remember the sabbath day, to keep it holy.

It is not to be used for man's flesh, and no other is to be made like it: holy it is, and you are to keep it holy.

And ye shall keep it holy day unto the LORD seven days in the year. And it shall be a law forever unto your children after you, that ye keep that feast in the seventh month.

Observe the sabbath day, to keep it holy, as Jehovah thy God commanded thee.
