'Sabbath day' in the Bible

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 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.
