'Sabbath Day' in the Bible

And while the children of Israel were in the wilderness, they found a man that gathered sticks upon the sabbath day.

And on the sabbath day two lambs of the first year without spot, and two tenth deals of flour for a meat offering, mingled with oil, and the drink offering thereof:

This is the burned offering for every Sabbath day, in addition to the regular burned offering, and its drink offering.
