“And in all things that I have said unto you be circumspect: and make no mention of the name of other gods, neither let it be heard out of thy mouth. Three times thou shalt keep a feast unto me in the year. Thou shalt keep the feast of unleavened bread: (thou shalt eat unleavened bread seven days, as I commanded thee, in the time appointed of the month Abib; for in it thou camest out from Egypt: and none shall appear before me empty:)”
- Exodus 23:13-15 (KJV)
