Nevertheless, we have just seen that Moses acknowledges that false prophets can predict things which will happen. And the Saviour warns us in the Gospel that at the end of the world several false prophets will arise, who will seduce many[194]--"They shall shew great signs and wonders, insomuch that, if it were possible, they shall deceive even the elect." It is not, then, precisely either the successful issue of the event which decides in favor of the false prophet--nor the default of the predictions made by true prophets which proves that they are not sent by God. Jonah was sent to foretell the destruction of Nineveh,[195] which did not come to pass; and many other threats of the prophets were not put into execution, because God, moved by the repentance of the sinful, revoked or commuted his former sentence. The repentance of the Ninevites guarantied them against the last misfortune. Isaiah had distinctly foretold to King Hezekiah[196] that he would not recover from his illness: "Set thine house in order, for thou shalt die, and not live." Nevertheless, God, moved with the prayer of this prince, revoked the sentence of death; and before the prophet had left the court of the king's house, God commanded him to return and tell the king that God would add yet fifteen years to his life. Moses assigns the mark of a true prophet to be, when he leads us to God and his worship--and the mark of a false prophet is, when he withdraws us from the Lord, and inclines us to superstition and idolatry. Balaam was a true prophet, inspired by God, who foretold things which were followed up by the event; but his morals were very corrupt, and he was extremely self-interested. He did everything he could to deserve the recompense promised him by the king of Moab, and to curse and immolate Israel.[197] God did not permit him to do so; he put into his mouth blessings instead of curses; he did not induce the Israelites to forsake the Lord; but he advised the Moabites to seduce the people of God, and cause them to commit fornication, and to worship the idols of the country, and by that means to irritate God against them, and draw upon them the effects of his vengeance. Moses caused the chiefs among the people, who had consented to this crime, to be hung; and caused to perish the Midianites who had led the Hebrews into it. And lastly, Balaam, who was the first cause of this evil, was also punished with death.[198]
