XII. (63) Therefore Moses, having become the most skilful herdsman of his time, and the most prudent provider of all the necessary things for his flock, and of all things which tended to their advantage, because he never delayed or hesitated, but exerted a voluntary and spontaneous cheerfulness in all things necessary for the animals under his charge, (64) saw his flocks increase with great joy and guileless good faith, so that he soon incurred the envy of the other herdsmen, who saw nothing in their own flocks resembling the condition of his; but they thought themselves well off if they continued as before, while the flock of Moses would have been thought to be falling off if it had not improved, every day, by reason of the vast augmentations that it was in the habit of receiving in beauty from its high condition and fatness, and in number from the prolific character of the females, and the wholesome way in which it was fed and managed. (65) And when Moses was leading his flock into a situation full of good water and good grass, where there was also a great deal of herbage especially suitable for sheep, he came upon a certain grove in a valley, where he saw a most marvellous sight. There was a bush or briar, a very thorny plant, and very weak and supple. This bush was on a sudden set in a blaze without any one applying any fire to it, and being entirely enveloped from the root to the topmost branch by the abundant flame, as though it had proceeded from some fountain showering fire over it, it nevertheless remained whole without being consumed, like some impassible essence, and not as if it were itself the natural fuel for fire, but rather as if it were taking the fire for its own fuel. (66) And in the middle of the flame there was seen a certain very beautiful form, not resembling any visible thing, a most Godlike image, emitting a light more brilliant than fire, which any one might have imagined to be the image of the living God. But let it be called an angel, because it merely related (die�ngelleto) the events which were about to happen in a silence more distinct than any voice by reason of the marvellous sight which was thus exhibited. (67) For the burning bush was a symbol of the oppressed people, and the burning fire was a symbol of the oppressors; and the circumstance of the burning bush not being consumed was an emblem of the fact that the people thus oppressed would not be destroyed by those who were attacking them, but that their hostility would be unsuccessful and fruitless to the one party, and the fact of their being plotted against would fail to be injurious to the others. The angel, again, was the emblem of the providence of God, who mitigates circumstances which appear very formidable, so as to produce from them great tranquillity beyond the hopes or expectation of any one.
