The Holy Convocations of Yahweh: When Yahweh says we are to celebrate His Feasts, He uses a Hebrew word that means appointed times or appointments. They are the Holy Convocations or Sacred Assemblies of Yahweh. There are 7 festivals that Yahweh prescribed in the Bible- 4 in the spring and 3 in the fall and the Shabbaths all year around. We can find them in the Leviticus 23.
