'On the Sabbath' in the Bible

And it shall be the prince's part to supply the burnt-offerings, and the oblation, and the drink-offering, at the feasts, and at the new moons, and on the sabbaths, in all the solemnities of the house of Israel: it is he that shall prepare the sin-offering, and the oblation, 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 this gate before Jehovah on the sabbaths and on the new moons.

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

And when the prince shall offer a voluntary burnt-offering or voluntary peace-offerings unto Jehovah, the gate that looketh toward the east shall be opened for him and he shall offer his burnt-offering and his peace-offerings as he did on the sabbath-day, and he shall go out again, and the gate shall be shut after he hath gone out.
