וְהָי֥וּ שָׁמֶ֛יךָ אֲשֶׁ֥ר עַל־רֹאשְׁךָ֖ נְחֹ֑שֶׁת וְהָאָ֥רֶץ אֲשֶׁר־תַּחְתֶּ֖יךָ בַּרְזֶֽל׃
И небеса твои над головой твои будут медными, а земля под тобою железными.
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.
