[294] While Asa was saying this, God gave him a signal of victory, and joining battle cheerfully on account of what God had foretold about it, he slew a great many of the Ethiopians; and when he had put them to flight, he pursued them to the country of Gerar; and when they left off killing their enemies, they betook themselves to spoiling them, (for the city Gerar was already taken,) and to spoiling their camp, so that they carried off much gold, and much silver, and a great deal of [other] prey, and camels, and great cattle, and flocks of sheep. Accordingly, when Asa and his army had obtained such a victory, and such wealth from God, they returned to Jerusalem. Now as they were coming, a prophet, whose name was Azariah, met them on the road, and bade them stop their journey a little; and began to say to them thus: That the reason why they had obtained this victory from God was this, that they had showed themselves righteous and religious men, and had done every thing according to the will of God; that therefore, he said, if they persevered therein, God would grant that they should always overcome their enemies, and live happily; but that if they left off his worship, all things shall fall out on the contrary; and a time should come, wherein no true prophet shall be left in your whole multitude, nor a priest who shall deliver you a true ,answer from the oracle; but your cities shall be overthrown, and your nation scattered over the whole earth, and live the life of strangers and wanderers. So he advised them, while they had time, to be good, and not to deprive themselves of the favor of God. When the king and the people heard this, they rejoiced; and all in common, and every one in particular, took great care to behave themselves righteously. The king also sent some to take care that those in the country should observe the laws also.
