'Seasons' in the Bible

Speak unto the sons of Israel, and thou hast said unto them, Appointed seasons of Jehovah, which ye proclaim, holy convocations, are these: they are My appointed seasons:

These are the feasts of the LORD, even holy convocations, which ye shall proclaim in their seasons.

These are appointed seasons of Jehovah, which ye proclaim holy convocations, to bring near a fire-offering to Jehovah, a burnt-offering, and a present, a sacrifice, and libations, a thing of a day in its day,

And Moses speaketh concerning the appointed seasons of Jehovah unto the sons of Israel.
