Leviticus 23:8, 12, 36

For seven days you will bring an offering made by fire to the LORD. There will be a holy meeting on the seventh day, and on that day you must not do any regular work.’ ”

“ ‘On the day when you present the bundle of grain, offer a male lamb, one year old, that has nothing wrong with it, as a burnt offering to the LORD.

You will bring an offering made by fire to the LORD each day for seven days. On the eighth day you will have another holy meeting, and you will bring an offering made by fire to the LORD. This will be a holy meeting; do not do any work.
