'Feast' in the Bible

In the first [month], in the fourteenth day of the month, you shall have the Passover, a feast of seven days; unleavened bread shall be eaten.

The seven days of the feast he shall prepare a burnt offering to Yahweh, seven bulls and seven rams without blemish daily the seven days; and a male goat daily for a sin offering.

In the seventh [month], in the fifteenth day of the month, in the feast, shall he do the like the seven days; according to the sin offering, according to the burnt offering, and according to the meal offering, and according to the oil.
