What does Deuteronomy 28:60 mean?

toward her young one who comes out from between her feet, and toward her children whom she bears; for she will eat them secretly for lack of all things, in the siege and in the distress with which your enemy will distress you in your gates.

If 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;

then 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.

Also every sickness and every plague, which is not written in the book of this law, Yahweh will bring them on you, until you are destroyed.

You will be left few in number, even though you were as the stars of the sky for multitude; because you didn’t listen to Yahweh your God’s voice.

It will happen that as Yahweh rejoiced over you to do you good, and to multiply you, so Yahweh will rejoice over you to cause you to perish, and to destroy you. You will be plucked from the land that you are going in to possess.
