'On the Sabbath' in the Bible

Behold, I am about to build a house for the name of Jehovah my God, to dedicate it to him, and to burn before him incense of sweet spices, and for the continual showbread, and for the burnt-offerings morning and evening, on the sabbaths, and on the new moons, and on the set feasts of Jehovah our God. This is an ordinance for ever 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 set 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 ye shall do: a third part of you, that come in on the sabbath, of the priests and of the Levites, shall be porters of the thresholds;

So the Levites and all Judah did according to all that Jehoiada the priest commanded: and they took every man his men, those that were to come in on the sabbath; with those that were to go out on the sabbath; for Jehoiada the priest dismissed not the courses.
