“These are the feasts of the LORD which you shall proclaim to be holy convocations, to offer an offering made by fire to the LORD, a burnt offering and a grain offering, a sacrifice and drink offerings, everything on its day-- besides the Sabbaths of the LORD, besides your gifts, besides all your vows, and besides all your freewill offerings which you give to the LORD.”
- Leviticus 23:37-38 (NKJV)
