'Sabbath' in the Bible

"Just as you did with my father David, sending him cedars to build him a palace to live in, do the same for me. Look, I'm building a temple dedicated to the name of the LORD my God, to his glory, so we can burn fragrant incense in his presence, display rows of the bread of his presence continuously, and make burnt offerings in the morning, evening, on Sabbath days, during New Moon festivals, and during appointed festivals scheduled by the LORD our God. This is mandated forever in Israel.

"Look! The king's son is going to rule, just as the LORD promised David's descendants. So here's what you'll need to do: One third of you priests and descendants of Levi who are on duty during the Sabbath will serve as guards at the temple gates.

What Jehoiada the priest ordered is precisely what the descendants of Levi and all of Judah did. Each of them took the men who were on duty on the Sabbath as well as those who were off duty. Jehoiada the priest did not release the divisions from service,

He also gave a portion of his own income for both morning and evening burnt offerings, for burnt offerings on the Sabbath, New Moons, and for the scheduled festivals, as is recorded in the LORD's Law.

All of this fulfilled what the LORD had predicted through Jeremiah. And so the land enjoyed its Sabbaths, and the length of the land's desolation lasted until a 70-year long Sabbath had been completed.
