'Feasts' in the Bible

As the holy flock, as the flock of Jerusalem in her set feasts, so shall the waste cities be filled with flocks of men: and they shall know that I am Jehovah.

And it shall be the prince's part to supply the burnt-offerings, and the oblation, and the drink-offering, at the feasts, and at the new moons, and on the sabbaths, in all the solemnities of the house of Israel: it is he that shall prepare the sin-offering, and the oblation, and the burnt-offering, and the peace-offerings, to make atonement for the house of Israel.

And when the people of the land come in before Jehovah in the set feasts, he that cometh in by the way of the north gate to worship shall go out by the way of the south gate; and he that cometh in by the way of the south gate shall go out by the way of the north gate: he shall not return by the way of the gate by which he came in, but shall go out straight before him.
