'Festival' in the Bible

“In the first month, on the fourteenth day of the month, you are to celebrate the Passover, a festival of seven days during which unleavened bread will be eaten.

During the seven days of the festival, he will provide seven bulls and seven rams without blemish as a burnt offering to the Lord on each of the seven days, along with a male goat each day for a sin offering.

At the festival that begins on the fifteenth day of the seventh month, he will provide the same things for seven days—the same sin offerings, burnt offerings, grain offerings, and oil.
