Ezekiel 20:12
“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.”
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.
But the house of Israel rebelled against me in the wilderness: they walked not in my statutes, and they despised my judgments, which if a man do, he shall even live in them; and my sabbaths they greatly polluted: then I said, I would pour out my fury upon them in the wilderness, to consume them.
But I wrought for my name’s sake, that it should not be polluted before the heathen, in whose sight I brought them out.
