Exodus 12:16 - Clarke's commentary and critical notes on the Bible

And in the first day there shall be an holy convocation, and in the seventh day there shall be an holy convocation to you; no manner of work shall be done in them, save that which every man must eat, that only may be done of you. In the first day and in the seventh day there shall be a holy convocation - This is the first place where we meet with the account of an assembly collected for the mere purpose of religious worship. Such assemblies are called holy convocations, which is a very appropriate appellation for a religious assembly; they were called together by the express command of God, and were to be employed in a work of holiness. מקרא mikra, convocation, is a word of similar import with the Greek εκκλησια, which we commonly translate Church, and which properly signifies an assembly convened by public call.
