in that same time, the Lord spoke by the hand of Isaiah, the son of Amoz, saying: "Go forth, and remove the sackcloth from your waist, and take your shoes from your feet." And he did so, going out naked and barefoot.
And this shall be: In that day, the prophets will be confounded, each one by his own vision, when he will prophesy. Neither will they be covered with a garment of sackcloth in order to deceive.
And he will go before him with the spirit and power of Elijah, so that he may turn the hearts of the fathers to the sons, and the incredulous to the prudence of the just, so as to prepare for the Lord a completed people."
