אַחֲרִ֤יב הָרִים֙ וּגְבָע֔וֹת וְכָל־עֶשְׂבָּ֖ם אוֹבִ֑ישׁ וְשַׂמְתִּ֤י נְהָרוֹת֙ לָֽאִיִּ֔ים וַאֲגַמִּ֖ים אוֹבִֽישׁ׃
I will make waste mountains and hills, And dry up all their herbs; And I will make the rivers islands, And will dry up the pools.
Read halakhic rulings (Jewish law) on Isaiah 42:15: and classical halakhic sources.
