WHAT IS THE MEANING OF ‘FEAST’ ?

Leviticus 23:2 Speak unto the children of Israel, and say unto them, Concerning the feasts <04150> of the LORD, which ye shall proclaim to be holy convocations, even these are my feasts <04150>

Leviticus 23:3 Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; you shall do no work therein: it is the sabbath of the LORD in all your dwellings.
