24. All these punishments of the Egyptians may be explained by an allegorical interpretation, according as one shall have chosen to understand them, and to compare them to the things whereunto they must be referred. Which we too will endeavour to do; and shall do it the more properly, the more we shall have been divinely aided. For to do this, those words of this Psalm do constrain us, wherein it was said, “I will open in parables my mouth, I will declare propositions from the beginning.” For for this cause even some things have been here spoken of, which that they befell the Egyptians at all we read not, although all their plagues are most carefully related in Exodus according to their order, so that while that which is not there mentioned we are sure hath not been mentioned in the Psalm to no purpose, and we can interpret the same only figuratively, we may at the same time understand that even the rest of the things which it is evident did happen, were done or described for the sake of some figurative meaning. For the Scripture doth so do in many passages of the prophetic sayings.…In the plagues therefore of the Egyptians, which are in the book which is called Exodus, where the Scripture hath been especially careful, that those things whereby they were afflicted should be all related in order, there is not found what this Psalm hath, “and He gave to the mildew their fruits.” This also wherein, when he had said, “and He gave over to the hail their beasts,” he hath added, “and their possession to the fire:” of the beasts slain with hail is read in Exodus; but how their possession was burned with fire, is not read at all. Although voices and fires do come together with hail, just as thunderings do commonly accompany lightnings; nevertheless, it is not written that anything was given over to the fire that it should be burned. Lastly, the soft things which the hail could not hurt, are said not to have been smitten, that is, hurt with hard blows; which things the locust devoured afterwards. Also that which is here spoken of, “and their mulberry trees with hoar-frost,” is not in Exodus. For hoar-frost doth differ much from hail; for in the clear winter nights the earth is made white with hoar-frost.
