Hearken unto me to hallow the Sabbath day

Thus saith the Lord; Take heed to yourselves, and bear no burden on the sabbath day, nor bring it in by the gates of Jerusalem;
Neither carry forth a burden out of your houses on the sabbath day, neither do ye any work, but hallow ye the sabbath day, as I commanded your fathers.
But they obeyed not, neither inclined their ear, but made their neck stiff, that they might not hear, nor receive instruction.
And it shall come to pass, if ye dilligently heaken unto me, saith the Lord, to bring no burden through the gates of this city on the sabbath day, but hallow the sabbath day, to do no work therein;
Then shall there enter into the gates of this city kings and princes sitting upon the throne of David, riding in chariots and on horses, they, and their princes , the men of Judah, and the inhabitants of Jerusalem: and this city shall remain for ever. ...
But if ye will not hearken unto me to hallow the sabbath day, and not bear a burden, even entering in at 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.

Jeremiah 17: 21-25, 27.
