Jerome : (Verse 12) And it will be, when it appears that Moab has labored in vain for his heights, he will enter his holy places to seek guidance, but he will not prevail. It is the ultimate misery, to not have support from those whom he has always revered. 'Deserted,' he says, 'are your strengths, and with all defenders slain, you will turn to idols, you will worship shrines, but you will not find help in them, as the devastation that is common with you arrives.' — Commentary on Isaiah Jerome : (Verse 12) But when he realizes that he has labored in vain in the lofty doctrines which he once believed, he will enter into his own holy things, not those things which are inherently holy, but those things which he erroneously thought were holy, and he will not be able to find help. Perhaps, in the desert of error and falsehood, he will attempt to enter into the holy Church, to make it his own, and to pray and beseech, but he will not prevail. For we cannot immediately, as we wish, attain perfect virtue. — Commentary on Isaiah
