'Feast' in the Bible

In the first month, in the fourteenth day of the month, ye have the passover, a feast of seven days, unleavened food is eaten.

And the seven days of the feast he prepareth a burnt-offering to Jehovah, seven bullocks, and seven rams, perfect ones, daily seven days, and a sin-offering, a kid of the goats, daily.

In the seventh month, in the fifteenth day of the month, in the feast, he doth according to these things seven days; as the sin-offering so the burnt-offering, and as the present so also the oil.
