What Does God Make a Holy Day?

The first time the word holy is ever used, and all the bible is right here. And what does god make holy time? If you were not an ancient mesopotamian, this would have leapt off the page into your mind if you were an original reader. Because in the ancient neres, the gods and the goddesses were found in space, not in time. Abraham joshua heschel puts it this way, the sabbaths are our great cathedrals. He called the seventh day architecture in time.
