'Sabbath' in the Bible

When the Israelites were in the wilderness they found a man gathering wood on the Sabbath day.

"'On the Sabbath day, you must offer two unblemished lambs a year old, and two-tenths of an ephah of finely ground flour as a grain offering, mixed with olive oil, along with its drink offering.

This is the burnt offering for every Sabbath, besides the continual burnt offering and its drink offering.
