'Feast' in the Bible

“Son of man, this is what the Lord God says: Tell every kind of bird and all the wild animals: Assemble and come! Gather from all around to My sacrificial feast that I am slaughtering for you, a great feast on the mountains of Israel; you will eat flesh and drink blood.

You will eat fat until you are satisfied and drink blood until you are drunk, at My sacrificial feast that I have prepared for you.

In the first month, in the fourteenth day of the month, ye shall have the passover, a feast of seven days; unleavened bread shall be eaten.

And seven days of the feast he shall prepare a burnt offering to the LORD, seven bullocks and seven rams without blemish daily the seven days; and a kid of the goats daily for a sin offering.

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