'On the Sabbath' in the Bible

And it shall be the prince's part to give the burnt-offerings, and the meal-offerings, and the drink-offerings, in the feasts, and on the new moons, and on the sabbaths, in all the appointed feasts of the house of Israel: he shall prepare the sin-offering, and the meal-offering, and the burnt-offering, and the peace-offerings, to make atonement for the house of Israel.

Thus saith the Lord Jehovah: The gate of the inner court that looketh toward the east shall be shut the six working days; but on the sabbath day it shall be opened, and on the day of the new moon it shall be opened.

And the people of the land shall worship at the door of that gate before Jehovah on the sabbaths and on the new moons.

And the burnt-offering that the prince shall offer unto Jehovah shall be on the sabbath day six lambs without blemish and a ram without blemish;

And when the prince shall prepare a freewill-offering, a burnt-offering or peace-offerings as a freewill-offering unto Jehovah, one shall open for him the gate that looketh toward the east; and he shall prepare his burnt-offering and his peace-offerings, as he doth on the sabbath day: then he shall go forth; and after his going forth one shall shut the gate.
