Leviticus 26:18, 21, 28

And if ye will not yet for all this hearken unto me, then I will punish you seven times more for your sins.

And if ye walk contrary unto me, and will not hearken unto me; I will bring seven times more plagues upon you according to your sins.

then I will walk contrary unto you also in fury; and I, even I, will chastise you seven times for your sins.
