18. If even after this you do not obey me, I will increase the chastisement for your sins sevenfold,
19. to break your proud strength. I will make the sky above you as hard as iron, and your soil as hard as bronze,
20. so that your strength will be spent in vain; your land will bear no crops, and its trees no fruit.
21. If then you continue hostile, unwilling to obey me, I will multiply my blows sevenfold, as your sins deserve.
