[118] When Solomon had said this, and had cast himself upon the ground, and worshipped a long time, he rose up, and brought sacrifices to the altar; and when he had filled it with unblemished victims, he most evidently discovered that God had with pleasure accepted of all that he had sacrificed to him, for there came a fire running out of the air, and rushed with violence upon the altar, in the sight of all, and caught hold of and consumed the sacrifices. Now when this Divine appearance was seen, the people supposed it to be a demonstration of God's abode in the temple, and were pleased with it, and fell down upon the ground and worshipped. Upon which the king began to bless God, and exhorted the multitude to do the same, as now having sufficient indications of God's favorable disposition to them; and to pray that they might always have the like indications from him, and that he would preserve in them a mind pure from all wickedness, in righteousness and religious worship, and that they might continue in the observation of those precepts which God had given them by Moses, because by that means the Hebrew nation would be happy, and indeed the most blessed of all nations among all mankind. He exhorted them also to be mindful, that by what methods they had attained their present good things, by the same they must preserve them sure to themselves, and make them greater and more than they were at present; for that it was not sufficient for them to suppose they had received them on account of their piety and righteousness, but that they had no other way of preserving them for the time to come; for that it is not so great a thing for men to acquire somewhat which they want, as to preserve what they have acquired, and to be guilty of no sin whereby it may be hurt.
