וּבָנוּ֙ חָרְב֣וֹת עוֹלָ֔ם שֹׁמְמ֥וֹת רִֽאשֹׁנִ֖ים יְקוֹמֵ֑מוּ וְחִדְּשׁוּ֙ עָ֣רֵי חֹ֔רֶב שֹׁמְמ֖וֹת דּ֥וֹר וָדֽוֹר׃
On se mettra à rebâtir les ruines antiques, à relever les décombres du passé, à restaurer les villes détruites, les éboulis des siècles écoulés.
Malbim
In the Second Discourse (Chapters 27 and 28), seeing that his companions have given up arguing, they having found no solution, Job returns to justifying the position he had previously taken in disagreeing with their theses and in refusing to accept propositions with which his mind cannot agree. To do otherwise would be hypocritical, and hypocrisy is hateful in the eyes of God. Better that he voice what he really thinks is the truth, even though it involves heretical and contrary notions, than he should flatter, spouting the opposite of what he really thinks, even though it might repair the remnants of faith and restore its desolation (Isaiah 61:4). (Ch.27:2-11)
