The Weekly Sabbath
23:3 “‘Six days work may be done, but on the seventh day there must be a Sabbath of complete rest, a holy assembly. You must not do any work; it is a Sabbath to the Lord in all the places where you live.
23:18 Along with the loaves of bread, you must also present seven flawless yearling lambs, one young bull, and two rams. They are to be a burnt offering to the Lord along with their grain offering and drink offerings, a gift of a soothing aroma to the Lord.
