⁵⁸If you will not observe to do all the words of this law that are written in this book, that you may fear this glorious and fearful name, YAHWEH YOUR GOD; ⁵⁹then Yahweh will make your plagues fearful, and the plagues of your offspring, even great plagues, and of long duration, and severe sicknesses, and of long duration.
