Ezekiel 20:12-13

12Also I gave them my Sabbaths as a sign between us, so they would know that I the LORD made them holy. 13“ ‘Yet the people of Israel rebelled against me in the wilderness. They did not follow my decrees but rejected my laws—by which the person who obeys them will live—and they utterly desecrated my Sabbaths. So I said I would pour out my wrath on them and destroy them in the wilderness.
