וְהָי֥וּ שָׁמֶ֛יךָ אֲשֶׁ֥ר עַל־רֹאשְׁךָ֖ נְחֹ֑שֶׁת וְהָאָ֥רֶץ אֲשֶׁר־תַּחְתֶּ֖יךָ בַּרְזֶֽל׃
Y tus cielos que están sobre tu cabeza, serán de metal; y la tierra que está debajo de ti, de hierro.
Targum Jonathan on Deuteronomy
And the heavens above you shall be as brass which sweateth, but that will not yield you any dew or rain; and the ground under you be as iron which sweateth not. nor maketh green the trees, nor yieldeth spiceries, fruits, nor herbs.
