'On the Sabbath' in the Bible

Behold, I build a house unto the name of Jehovah my God to dedicate it to him, to burn before him sweet incense, and for the continual arrangement of the shewbread, and for the morning and evening burnt-offerings and 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 at the set feasts, three times in the year, at the feast of unleavened bread, and at the feast of weeks, and at the feast of tabernacles.

This is the thing which ye shall do: a third part of you that come in 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 that Jehoiada the priest commanded; and they took every man his men, those that were to come in on the sabbath, with them that were to go forth on the sabbath; for Jehoiada the priest did not liberate the divisions.
