אָ֚ז אַשְׁקִ֣יעַ מֵֽימֵיהֶ֔ם וְנַהֲרוֹתָ֖ם כַּשֶּׁ֣מֶן אוֹלִ֑יךְ נְאֻ֖ם אֲדֹנָ֥י יְהוִֽה׃
Allora farò calmare le loro acque e farò scorrere i loro fiumi come petrolio, dice l'Eterno DIO.
Rashi on Ezekiel
I shall sink their waters The foot of cattle will not make it murky, and the mud will sink, so that the water will be clear and clean like refined oil.
