Ezekiel 20:5, 7, 19-20

and say to them, Thus says the Lord GOD: On the day when I chose Israel, I swore to the offspring of the house of Jacob, making myself known to them in the land of Egypt; I swore to them, saying, I am the LORD your God.

And I said to them, ‘Cast away the detestable things your eyes feast on, every one of you, and do not defile yourselves with the idols of Egypt; I am the LORD your God.’

I am the LORD your God; walk in my statutes, and be careful to obey my rules, and keep my Sabbaths holy that they may be a sign between me and you, that you may know that I am the LORD your God.’
