The veneration of angels and the attribution to them of especial days or months, as well as the idea that they were guardians of those born on those days or during those months, was the result of many factors. The belief in the existence of angels is present in all parts of the Bible, but in the earlier portions they are not individualized in any way. The angel of God, or of the Lord ( malach Elohim or malach Yahveh ) was simply a messenger of God, employed to communicate his will or else to accomplish some act of divine justice. It is quite possible that the greater prominence given to angels among the Jews after the Babylonian Captivity was not solely dependent upon Babylonian or Persian influence. We learn from the historical and prophetical books of the Old Testament that the Jews had, from the earliest times, worshipped other gods besides the God of Israel, and were ever ready to assimilate the religious superstitions of the heathen world. Several of the divinities that were worshipped in Babylonia and Assyria were also objects of adoration in Israel, not indeed by the chosen spirits of the nation from whom we receive our records, but by the masses of the people. This very fact, however, served in a certain sense to maintain the purity of the national religion. As the superstitious inclinations of the populace were so fully satisfied from without, there was no necessity to develop or distort the national religion in this direction. The Babylonian Captivity changed all this. It was the élite of the Jewish nation that was deported, and the sufferings and humiliations to which they were subjected in a foreign land only served to strengthen their faith in Yahveh and in his Law. Hence it is, that when this tried and purified remnant returned to Judæa, rebuilt the fallen temple and reorganized the state, the latter became a theocracy in a much stricter sense than ever before, and from this time we can really speak of Judaism as the religion of the whole people.
