And as a further proof, they say that there is no mention made of any religious act of the people of Israel while in the wilderness; neither the celebration of the Passover, nor of the Feast of the Tabernacles, nor of any public form of worship being established, nor even the practice of circumcision, the seal of the covenant made by God with Abraham.

They likewise refer to the history of Joshua, where this great conqueror thus addresses the Jews: “If it seem evil unto you to serve the Lord, choose you this day whom you will serve; whether the gods which your fathers served in Mesopotamia or the gods of the Amorites, in whose land ye dwell:” and the people said, “Nay, but we will serve the Lord our God (Adonai).” And Joshua said unto the people, “Ye have chosen, now therefore put away the strange gods which are among you.” Hence, say they, it is evident that the Israelites had other gods besides the Lord (Adonai) under Moses.

It is altogether needless to take up the reader’s time with an attempt to refute the opinions of those critics who think that the Pentateuch was not written by Moses. This subject has been sufficiently discussed long ago; and, even admitting that some few parts of it were written in the times of the Judges, the Kings, or the Prophets, it would not make the whole less inspired or divine. It is sufficient, in my opinion, if the Holy Scripture proves to us, that, notwithstanding the extraordinary punishments which the Jews called down upon themselves by their idolatrous worship of the golden calf, they continued for a long time to enjoy perfect liberty of conscience; and it is even probable, that Moses, after having massacred the twenty-three thousand, in the first transports of his rage against his brother and them for having erected this idol, finding that nothing was to be gained by such severity in matters of religion, was glad to wink at the fondness the people expressed for strange gods.

And indeed he himself appears soon after to have transgressed the very law which he had given:[40] for, notwithstanding his having forbidden all molten or graven images, we find him erecting the brazen serpent. And this law was again dispensed with by Solomon in the building of his temple; where that prince caused twelve brazen bulls to be placed as supporters to the great Laver; as also cherubim in the ark, which had two heads, one of an eagle and the other of a calf; and it was probable from this latter head, badly made, and found in the temple by the Roman soldiers at the time of their plundering of it, that the Jews were so long reported to have worshipped an ass. Moreover, notwithstanding the repeated prohibitions against the worship of false gods, Solomon, though giving way to the grossest idolatry, lived and died in peace. Jeroboam, to whom God himself gave ten parts out of twelve of the kingdom, set up two golden calves, and yet reigned two and twenty years, having united in his person the twofold dignity of monarch and of high-priest. The petty people of Judæa erected altars and images to strange gods under Rehoboam. Pious King Aza suffered the high places to remain undemolished. And lastly, Uriah, the high-priest, erected a brazen altar, which had been sent to him by the king of Syria, in the temple, in the place of the altar of burnt-offerings. In a word, we do not anywhere find the least constraint in point of religion among the Jews; it is true, indeed, that they frequently destroyed and murdered one another; but that was from motives of political concern, and not about the modes of belief. It is true, that among the prophets we find some making heaven a party in their vengeance. Elias, for instance, calls down fire from heaven to consume the priests of Baal. And Elisha sent bears to devour two and forty little children for calling him baldhead. But these miracles are very rare in their kind, and it would moreover be somewhat inhuman to desire to imitate them. We are also told that the Jews were a most ignorant and cruel people; and that in their war with the Midianites[41] they were commanded by Moses to kill all the male children and all the child-bearing women, and to divide the spoil.[42] They found in the enemy’s camp 675,000 sheep, 72,000 oxen, 61,000 asses, and 32,000 young maidens, and they took all the spoil and slew the captives. Several commentators will have it, that thirty-two of the young women were sacrificed to the Lord. “The Lord’s tribute was thirty and two persons.”[43]
