Ezekiel 20:8-12

But they rebelled against me, and would not hearken unto me: they did not every man cast away the abominations of their eyes, neither did they forsake the idols of Egypt: then I said, I will pour out my fury upon them, to accomplish my anger against them in the midst of the land of Egypt.

But I wrought for my name’s sake, that it should not be polluted before the heathen, among whom they were, in whose sight I made myself known unto them, in bringing them forth out of the land of Egypt.

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

And I gave them my statutes, and shewed them my judgments, which if a man do, he shall even live in them.

Moreover also I gave them my sabbaths, to be a sign between me and them, that they might know that I am the LORD that sanctify them.
