A brief enumeration of the chief festivals among the Israelites is called for in the present connexion because they were agricultural feasts; and, as has already been pointed out incidentally, one of the purposes of the sacred dance was to ensure good crops. All that we learn as to the character of these festivals in the Old Testament emphasizes the element of rejoicing during their celebration; and this applies with special force to the feast of Tabernacles. The dancing which took place at these feasts would, therefore, seem to have been purely expressions of joy. But there are reasons for believing that other elements entered in as well. Expressions of thanksgiving to a god are at the same time a means of honouring him; and this, we may feel certain, figured largely at the Israelite feasts; they were thankful to Jahwe for the fruits of the field, and they were joyful for plenty; so that when grateful joy expressed itself in the dance it constituted an act of honouring, and therefore of worshipping, the national God. The rare explicit mention of these dances during the feasts in the Old Testament is easily accounted for. But the cultural stage of the bulk of the Israelite people, at the very least up to the time of the Exile, can be proved by many indications in the Old Testament to have been no higher than other races; the extremely significant fact recorded by one of the prophets that, on occasion, the most barbarous form of the ecstatic dance, with its self-inflicted lacerations and blood-flowing, was practised by the people for the purpose of ensuring good crops, offers ample justification for the belief that one of the objects of the sacred dance at the spring festival was likewise to ensure good crops. The rite was a world-wide one, which is in itself presumptive evidence that it was practised by the Israelites. The importance of the sacred dance during the Jewish feasts of later times, for the existence of which the evidence is ample, must be regarded as the observance of traditional custom. The ancient Arabs did not cultivate the soil and therefore did not celebrate festivals of this kind. Among some modern Arabs dancing takes place at circumcision festivals, and it is accompanied by song; there are grounds for believing that the Israelites did the same. The dance in this case must be regarded as having been performed in honour of the newly initiated, who, by circumcision, were admitted into the community of the tribe[284]. Among the Egyptians both national and local Harvest festivals were celebrated; during these the sacred dance played an important part. We may take it that, as among the Israelites, the purpose of these dances was to express joyful gratitude to the god of fertility. The “Sed” festival was another occasion on which a sacred dance was performed; the deified king was honoured in this way.
