Jamieson, Fausset and Brown on Ezekiel 7:19

19. cast ... silver in ... streets--just retribution; they had abused their silver and gold by converting them into idols, "the stumbling-block of their iniquity" (Eze 14:3, 4, that is, an occasion of sinning); so these silver and gold idols, so far from "being able to deliver them in the day of the Lord's wrath" (see Pr 11:4), shall, in despair, be cast by them into the streets as a prey to the foe, by whom they shall be "removed" (Grotius translates as the Margin, "shall be despised as an unclean thing"); or rather, as suits the parallelism, "shall be put away from them" by the Jews [Calvin]. "They (the silver and gold) shall not satisfy their souls," that is, their cravings of appetite and other needs.
