Leviticus 26:18-20

Amplified Bible

¹⁸ If in spite of all this you still will not listen to Me and be obedient, then I will punish you seven times more for your sins. ¹⁹ I will break your pride in your power, and I will make your sky like iron [giving no rain and blocking all prayers] and your ground like bronze [hard to plow and yielding no produce].^{(A) 20} Your strength will be spent uselessly, for your land will not yield its produce and the trees of the land will not yield their fruit.
