Numbers 15:30-34

But the soul that doeth ought presumptuously, whether he be born in the land, or a stranger, the same reproacheth the LORD; and that soul shall be cut off from among his people.

Because he hath despised the word of the LORD, and hath broken his commandment, that soul shall utterly be cut off; his iniquity shall be upon him.

And while the children of Israel were in the wilderness, they found a man that gathered sticks upon the sabbath day.

And they that found him gathering sticks brought him unto Moses and Aaron, and unto all the congregation.

And they put him in ward, because it was not declared what should be done to him.
