7891. And there shall be to you in the first day a holy convocation. That this signifies that in the beginning all shall be together, is evident from the signification of “the first day,” as being the beginning, namely, of liberation from those who have infested, and thus from damnation; and from the signification of “a holy convocation,” as being that all shall be together. Convocations took place in order that the whole assemblage of Israel might be together, and might thus represent heaven; for they were then all distinguished into tribes, and the tribes into families, and the families into houses. (That heaven along with the societies there was represented by the tribes, the families, and the houses of the sons of Israel, see n. 7836.) Therefore those convocations were called holy, and took place at every feast (Leviticus 23:27, 36; Numbers 28:26; 29:1, 7, 12). From this the feasts themselves were called “holy convocations,” for it was commanded that all the males should be present at them. That the feasts were called “holy convocations” is evident in Moses:

These are the set feasts of Jehovah, which ye shall call holy convocations, to offer a fire-offering unto Jehovah (Leviticus 23:37).

That at such times all males were to be present, in the same:

Three times in a year shall every male of thine appear together before Jehovah thy God, in the place which He shall choose; in the feast of unleavened things, and in the feast of weeks, and in the feast of tabernacles (Deuteronomy 16:16).

7996. No son of an alien shall eat of it. That this signifies that those who are not in truth and good are to be separated from them, is evident from the signification of “an alien,” as being those out of the church who do not acknowledge anything of the truth and good of faith, as was the case with the nations in the land of Canaan (see n. 2049, 2115), thus who are not in truth and good; and from the signification of “not eating of it,” as being to communicate and be conjoined with them, thus to be separated from them. In what now follows those are treated of who should eat the passover together, and those who should not. The supper of the passover represented the consociations of the good in heaven; and in the statutes which follow, it is declared who could be consociated and who could not. In general, feasts, both dinners and suppers, in ancient times were made within the church in order that they might be consociated and conjoined as to love, and that they might instruct one another in those things which are of love and faith, thus in the things of heaven (see n. 3596, 3832, 5161). Such at that time were the delights attending their banquets, and such was the end for the sake of which were their dinners and suppers. Thus the mind and the body also were nourished unanimously and correspondently; and from this they had health and long life, and from it they had intelligence and wisdom; and also from this they had communication with heaven, and some had open communication with angels. But as in course of time all internal things vanish away and pass into external ones, so also did the purposes of the feasts and banquets, which at this day are not for the sake of any spiritual conjunction, but for the sake of worldly conjunctions, namely, for the sake of gain, for the sake of the pursuit of honors, and for the sake of pleasures, from which there is nourishment of the body, but none of the mind.
