Ezekiel 20:11

But I worked for my name's sake, that it should not be profaned in the sight of the nations, among which they were, in whose sight I made myself known to them, in bringing them forth out of the land of Egypt.

So I caused them to go forth out of the land of Egypt, and brought them into the wilderness.

Moreover also I gave them my Sabbaths, to be a sign between me and them, that they might know that I am Yahweh who sanctifies them.

But the house of Israel rebelled against me in the wilderness: they didn't walk in my statutes, and they rejected my ordinances, which if a man keep, he shall live in them; and my Sabbaths they greatly profaned. Then I said I would pour out my wrath on them in the wilderness, to consume them.
