But if this personification seems to any one strange, he must consider how incredible seemed to be what the Prophet here teaches, and how difficult it was to produce a conviction on the subject. We indeed confess that God is the judge of the world; nay, there is no one who does not anticipate his judgement by condemning avarice and cruelty; the very name of avarice is infamous and hated by all: the same may be said of cruelty. But yet
when we see the avaricious in splendor and in esteem, we are astounded, and no one is able to foresee by faith what the Prophet here declares. Since, then our dullness is so great, or rather our sottishness, it is no wonder that the Prophet should here set before us the stones and the wood, as though he said, “When all prophecies and all warnings become frigid, and God himself obtains no credit, while openly declaring what he will do, and when his servants consume their labor in vain by warning
and crying, let now the stones come forth, and be teachers to you who will not give ear to the voice of God himself, and let the wood also cry out in its turn.” This, then, is the reason why the Prophet introduces here mute things as the speakers, even to awaken our insensibility.
