Eastern Orthodoxy: Taking All the Fun Out of Holidays Since 1,500 BC

Exodus 19:15 And he said unto the people: Be ready against the third day: come not at your wives. 16 ¶And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled. 17 And Moses brought forth the people out of the camp to meet with God; and they stood at the nether part of the mount. 18 And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly. 19 And when the voice of the trumpet sounded long, and waxed louder and louder, Moses spake, and God answered him by a voice. 20 And the LORD came down upon mount Sinai, on the top of the mount: and the LORD called Moses up to the top of the mount; and Moses went up.

1 Samuel 21:4 And the priest answered David, and said: There is no common bread under mine hand, but there is hallowed bread ; if the young men have kept themselves at least from women. 5 And David answered the priest, and said unto him: Of a truth women have been kept from us about these three days, since I came out, and the vessels of the young men are holy, and the bread is in a manner common, yea, though it were sanctified this day in the vessel. 6 So the priest gave him hallowed bread: for there was no bread there but the shewbread, that was taken from before the LORD, to put hot bread in the day when it was taken away.
