Leviticus 26:16-20

¹⁶I also will do these things to you: I will quickly visit you with poverty, and burning heat, which shall waste your eyes, and consume your lives. You shall sow your seed in vain, which shall be devoured by your enemies.

¹⁷I will set my face against you, and you shall fall down before your enemies, and shall be made subject to them that hate you, you shall flee when no man pursueth you.

¹⁸But if you will not yet for all this obey me: I will chastise you seven times more for your sins,

¹⁹And I will break the pride of your stubbornness, and I will make to you the heaven above as iron, and the earth as brass:

²⁰Your labour shall be spent in vain, the ground shall not bring forth her increase, nor the trees yield their fruit.
