Ezekiel 20:12

“But as for you, speak to the sons of Israel, saying, ‘You shall surely keep My sabbaths; for this is a sign between Me and you throughout your generations, that you may know that I am Yahweh who makes you holy.

“It is a sign between Me and the sons of Israel forever; for in six days Yahweh made heaven and earth, but on the seventh day He rested and was refreshed.”

“How blessed is the man who does this, And the son of man who takes hold of it, Who keeps from profaning the sabbath, And keeps his hand from doing any evil.”

“You shall not bring a load out of your houses on the sabbath day nor do any work, but keep the sabbath day holy, as I commanded your fathers.

and I pronounced them unclean because of their gifts, in that they caused all their firstborn to pass through the fire so that I might make them desolate, in order that they might know that I am Yahweh.”’

“And the nations will know that I am Yahweh who sanctifies Israel, when My sanctuary is in their midst forever.”’”

“And in a dispute, they shall take their stand to judge; they shall judge it according to My judgments. They shall also keep My laws and My statutes in all My appointed times and keep My sabbaths holy.
