'On the Sabbath' in the Bible

Behold, I am building a house to the name of Jehovah my God, to dedicate it to Him, and to burn before Him sweet incense, and for the continual showbread, and for the burnt offerings morning and evening, on the sabbaths, and on the new moons, and on the solemn feasts of Jehovah our God. This is an ordinance forever to Israel.

even as the duty of every day required, offering according to the commandment of Moses, on the sabbaths and on the new moons, and on the solemn feasts, three times in the year, even in the Feast of Unleavened Bread, and in the Feast of Weeks, and in the Feast of Tabernacles.

This is the thing that you shall do. A third part of you entering on the sabbath, of the priests and of the Levites, shall be keepers of the doors.

And the Levites and all Judah did according to all things that Jehoiada the priest had commanded. And every man took his men who were to come in on the sabbath, with the ones who were to go out on the sabbath. For Jehoiada the priest did not dismiss the divisions.
