Numbers 15:36

“Six days work may be done, but on the seventh day you shall have a holy day, a sabbath of complete rest to Yahweh; whoever does any work on it shall be put to death.

“You shall also say to the sons of Israel: ‘Any man from the sons of Israel or from the sojourners sojourning in Israel who gives any of his seed to Molech shall surely be put to death; the people of the land shall stone him with stones.

“Then all the men of his city shall stone him, and he will die; so you shall purge the evil from your midst, and all Israel will hear of it and fear.

‘Thus says Yahweh, “Take care of yourselves, and do not carry any load on the sabbath day or bring anything in through the gates of Jerusalem.

And if the first piece of dough is holy, the lump is also; and if the root is holy, the branches are too.
