This is the reason why the Prophet now says, Apply your heart, and then adds, Go up to the mountain, bring wood, etc. And this passage strikingly sets forth why God punished their sins, in order that they might not only perceive that they had sinned, but that they might also seek to amend that which displeased God. We may also, in the second place, learn from what is said, how we are to proceed rightly in the course of true repentance. The beginning is, that our sins should become displeasing to us; but if any of us proceed no farther, it will be only an evanescent feeling: it is therefore necessary to advance to the second step; an amendment for the better ought to follow. The Prophet expresses both here: He says first, Lay your heart on your ways; that is, “Consider whence comes this famine to you, and then how it is that by laboring much ye gain nothing, except that God is angry with you.” Now this was what wisdom required. But he again repeats the same thing, Lay your heart on your ways, that is, “Not only that sin may be hated by you, but also that this sloth, which has hitherto offended God and provoked his wrath, may be changed into strenuous activity.” Hence he says, Go up to the mountain, and bring wood, and let the house be built
