Set Apart
In modern language, "holy" often means something religious or spiritual. But in the Bible, “holy” simply means “set apart.” It means something (or someone) different and distinct from everything else.
God is unlike any other gods the nations knew. The Lord is holy and called His people to be distinct—or holy—too.
Some of the distinctions that set the Israelite practices apart were religious and spiritual. They offered sacrifices in a certain way and had specific instructions for how priests, worship, and the temple operated. Other practices that set Israel apart involved everyday things, like food, clothing, and their weekly calendars. These habits and customs were meant to reflect and reinforce that they were truly different—or holy—because they belonged to God.
The fourth commandment given to Israel is to "remember the Sabbath day" and keep it holy—a reminder to Israel of the blessed pattern God laid out in Creation. Just as our Holy Creator worked for six days and rested on a seventh, He calls His holy people to do the same.
What's holy about the Sabbath? It's a day set apart to be different from all the other days of the week. God intends for one day a week to look and feel different. As people who belong to Him, we can delight in His designation of some days as productive days for work and then other days set apart for reflection and refreshment.
Remember, God created special times for rest—keep those times set apart.

And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: him God raised up the third day, and shewed him openly; not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. And he commanded us to preach unto the people, and to testify that it is he ...
