Leviticus 26:16-20

I, in turn, will do this to you: I will summon a sudden terror against you, consumption and fever that will make the eyes fail and the soul languish; also, you will sow your seed uselessly, for your enemies will eat it.

And I will set My face against you so that you will be defeated before your enemies; and those who hate you will rule over you, and you will flee when no one is pursuing you.

If also after these things you do not obey Me, then I will punish you seven times more for your sins.

I will also break down your pride of power; and I will make your sky like iron and your earth like bronze.

Your strength will be consumed uselessly, for your land will not yield its produce and the trees of the land will not yield their fruit.
