'On the Sabbath' in the Bible

thus saith Jehovah: Take heed to your souls, and bear no burden on the sabbath day, and bring nothing in through the gates of Jerusalem;

and carry forth no burden out of your houses on the sabbath day, neither do any work; but hallow ye the sabbath day, as I commanded your fathers,

And it shall come to pass, if ye diligently hearken unto me, saith Jehovah, to bring in no burden through the gates of this city on the sabbath day, and to hallow the sabbath day, to do no work therein;

But if ye will not hearken unto me, to hallow the sabbath day and not to bear a burden and enter in through the gates of Jerusalem on the sabbath day, then will I kindle a fire in the gates thereof, and it shall devour the palaces of Jerusalem, and it shall not be quenched.
