14 Let us come now, O King, to the history of the Jews also, and see what opinion they have as to God. The Jews then say that God is one, the Creator of all, and omnipotent; and that it is not right that any other should be worshipped except this God alone. And herein they appear to approach the truth more than all the nations, especially in that they worship God and not His works. And they imitate God by the philanthropy which prevails among them; for they have compassion on the poor, and they release the captives, and bury the dead, and do such things as these, which are acceptable before God and well-pleasing also to men—which (customs) they have received from their forefathers.
Nevertheless they too erred from true knowledge. And in their imagination they conceive that it is God they serve; whereas by their mode of observance it is to the angels and not to God that their service is rendered:— as when they celebrate sabbaths and the beginning of the months, and feasts of unleavened bread, and a great fast; and fasting and circumcision and the purification of meats, which things, however, they do not observe perfectly.
