18 And if in spite of this you will not listen to me, then I will discipline you again ^xsevenfold for your sins, 19 and I will break ^ythe pride of your power, and I ^zwill make your heavens like iron and your earth like bronze. 20 And ^ayour strength shall be spent in vain, for ^byour land shall not yield its increase, and the trees of the land shall not yield their fruit.
