1 Nephi 14:17

And when the day cometh that the wrath of God is poured out upon the mother of harlots, which is the great and abominable church of all the earth, whose founder is the Devil, then, at that day, the work of the Father shall commence, in preparing the way for the fulfilling of his covenants, which he hath made to his people, which are of the House of Israel.

When the day comes that God’s anger is poured out on the mother of prostitutes, which is the great and evil church of all the earth whose founder is the devil, then the Father’s work will begin. He will prepare the way to fulfill his promises to his people who are of the House of Israel.

“When the day comes that God pours out his anger on the mother of prostitutes—the great evil church of all the earth that the Devil founded—on that day the Father will start preparing the way to fulfill his promises to his people of the House of Israel.”
