Jeremiah 17:19-22

19 Thus said Yahweh to me: Go, and stand in the gate of the children of the people, through which the kings of Judah come in, and by which they go out, and in all the gates of Jerusalem;  20 and tell them, Hear you the word of Yahweh, you kings of Judah, and all Judah, and all the inhabitants of Jerusalem, that enter in by these gates:  21 Thus says Yahweh, Take heed to yourselves, and bear no burden on the Sabbath day, nor bring it in by the gates of Jerusalem;  22 neither carry forth a burden out of your houses on the Sabbath day holy, neither do any work: but make the Sabbath day, as I commanded your fathers.
