Leviticus 26:18-21

¹⁸And if, even after these things, you will not give ear to me, then I will send you punishment seven times more for your sins.

¹⁹And the pride of your strength will be broken, and I will make your heaven as iron and your earth as brass;

²⁰And your strength will be used up without profit; for your land will not give her increase and the trees of the field will not give their fruit.

²¹And if you still go against me and will not give ear to me, I will put seven times more punishments on you because of your sins.
