Ezekiel 20:12-13

MLV(i) 12 Moreover I also gave them my Sabbaths, to be a sign between me and them, that they might know that I am Jehovah who sanctifies them.
13 But the house of Israel rebelled against me in the wilderness. They did not walk in my statutes and they rejected my ordinances, which if a man keeps, he will live in them. And they greatly profaned my Sabbaths. Then I said I would pour out my wrath upon them in the wilderness, to consume them.
