Leviticus 26:18, 21, 28

“And if, in spite of all this, you still disobey me, I will punish you seven times over for your sins.

“If even then you remain hostile toward me and refuse to obey me, I will inflict disaster on you seven times over for your sins.

then I will give full vent to my hostility. I myself will punish you seven times over for your sins.
