'Convocations' in the Bible

Do not bring any more meaningless offerings; I consider your incense detestable! You observe new moon festivals, Sabbaths, and convocations, but I cannot tolerate sin-stained celebrations!

Then the Lord will create over all of Mount Zion and over its convocations a cloud and smoke by day and a bright flame of fire by night; indeed a canopy will accompany the Lord's glorious presence.
