That is because the Lord worked six days and made the sky, the earth, the sea, and everything in them. And on the seventh day, he rested. In this way the Lord blessed the Sabbath—the day of rest. He made that a very special day.
The Sabbath will be a sign between me and the Israelites forever.’” (The Lord worked six days and made the sky and the earth, and on the seventh day he rested and relaxed.)
God gave us the ability to think about his world, but we can never completely understand everything he does. And yet, he does everything at just the right time.
God blessed the seventh day and made it a holy day. He made it special because on that day he rested from all the work he did while creating the world.
