'Sabbath Day' in the Bible

And yet the house of Israel rebelled against me in the wilderness. They would not walk in my commandments; they have cast away my laws, which whoso keepeth should live in them; and my Sabbath days have they greatly unhallowed. Then I made me to pour out my indignation upon them, and to consume them in the wilderness.

Notwithstanding, their sons rebelled against me also: they walked not in my statutes, they kept not my laws to fulfill them, which he that doth shall live in them; neither hallowed they my Sabbath days. Then I made me again to pour out my indignation over them, and to satisfy my wrath upon them in the wilderness.

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 offer unto the LORD in the sabbath day shall be six lambs without blemish, and a ram without blemish.

Now when the prince shall prepare a voluntary burnt offering or peace offerings voluntarily unto the LORD, one shall then open him the gate that looketh toward the east, and he shall prepare his burnt offering and his peace offerings, as he did on the sabbath day: then he shall go forth; and after his going forth one shall shut the gate.
