אֶפְתַּ֤ח עַל־שְׁפָיִים֙ נְהָר֔וֹת וּבְת֥וֹךְ בְּקָע֖וֹת מַעְיָנ֑וֹת אָשִׂ֤ים מִדְבָּר֙ לַאֲגַם־מַ֔יִם וְאֶ֥רֶץ צִיָּ֖ה לְמוֹצָ֥אֵי מָֽיִם׃
I will open rivers on the high hills, And fountains in the midst of the valleys; I will make the wilderness a pool of water, And the dry land springs of water.
