Jerome : And, like doves, we groan, without sense and understanding of the Scriptures, only meditating on words that we recite from memory. But just as the doves, of which it is written: Ephraim is like a dove without sense (Hosea 7:11); and just as in the Gospel, simplicity is set against the malice of serpents (Matthew 10): so in the present place, simplicity without prudence, which is close to foolishness, is shown in the meditation on words alone. — Commentary on Isaiah Jerome : We roar like bears, all of us: and we moan like doves, meditating. We waited for judgment, and it does not come: for salvation, and it is far from us. LXX: They shall be like a bear and a dove walking together. We hoped for judgment, but there is none; salvation has far from us. He says, let us roar like bears, and let us moan like doves; that they may be equally cruel and miserable: fierce and savage towards the humble and submissive: fearful and trembling before those who are stronger, whom they dread like hawks. We also read in another place: Like a bear robbed of her cubs. And in Daniel, a bloody kingdom compared to the fiercest bears (2 Kings 17:8; Dan. 7). And, like doves, we groan, without sense and understanding of the Scriptures, only meditating on words that we recite from memory. But just as the doves, of which it is written: Ephraim is like a dove without sense (Hosea VII, 11); and just as in the Gospel, simplicity is set against the malice of serpents (Matthew X): so in the present place, simplicity without prudence, which is close to foolishness, is shown in the meditation on words alone. They will await judgment, and it will not come. Salvation is implied: they will wait and it will not come, because she has migrated far away to the nations. In this, it should be noted that everything is said in the future tense, so that what the Jews are now enduring is indicated. — Commentary on Isaiah
