'On the Sabbath' in the Bible

It shall be the prince’s part to provide the burnt offerings, the grain offerings and the drink offerings, at the feasts, on the new moons and on the sabbaths, at all the appointed feasts of the house of Israel; he shall provide the sin offering, the grain offering, the burnt offering and the peace offerings, to make atonement for the house of Israel.”

‘Thus says the Lord God, “The gate of the inner court facing east shall be shut the six working days; but it shall be opened on the sabbath day and opened on the day of the new moon.

The people of the land shall also worship at the doorway of that gate before the Lord on the sabbaths and on the new moons.

The burnt offering which the prince shall offer to the Lord on the sabbath day shall be six lambs without blemish and a ram without blemish;

When the prince provides a freewill offering, a burnt offering, or peace offerings as a freewill offering to the Lord, the gate facing east shall be opened for him. And he shall provide his burnt offering and his peace offerings as he does on the sabbath day. Then he shall go out, and the gate shall be shut after he goes out.
