Sabbath

Exodus 31:13 "Tell the Israelites this: 'You must follow the rules about my special days of rest. You must do this because they will be a sign between you and me for all generations. This will show you that I, the LORD, have made you my special people.

The Israelites must remember the Sabbath and make it a special day. They must continue to do this forever. It is an agreement between them and me that will continue forever.
The Sabbath will be a sign between me and the Israelites forever.'"

Ezekiel 20:12 I also told them about all the special days of rest, which were a special sign between us. They showed that I am the LORD and that I was making them special to me.

20:20 Show that my days of rest are important to you. Remember, they are a special sign between us. I am the LORD, and these days show you that I am your God."

Isaiah 66:21 I will also choose some of these people to be priests and Levites." The LORD himself said this.
The LORD says, "I will make a new world—new heavens and a new earth—that will last forever. In the same way, your names and your children will always be with me.
Everyone will come to worship me on every worship day; they will come every Sabbath and every first day of the month. This is what I, the LORD, have said.

Your cities have been destroyed for many years, but you will rebuild them and their foundations will last for a long time. You will be called "Fence Fixer" and "Builder of Roads and Houses."
That will happen when you stop sinning against God's law about the Sabbath and when you stop doing things to please yourself on that special day. You should call the Sabbath a happy day. You should honor the LORD'S special day by not saying and doing things that you do every other day of the week.
Then you could enjoy the LORD. As the LORD himself says, "I could carry you up to the highest mountain and let you enjoy the land that I gave to your father Jacob."
