[That] thou hast also built unto thee an eminent place,.... Or a "brothel" ; and so the Septuagint version, "a whoring house"; not content to commit idolatry privately, they built a public place for idolatrous worship.
The Targum renders it, "altar", The word has the signification of a pit or ditch; with which compare Pr 22:14;and hast made thee an high place in every street; of Jerusalem, and other cities; it was usual to erect high places in streets, where altars were built, and idols set up to be worshipped: it denotes the public manner in which they committed idolatry, and the multitude of their idols; which shows their impudence and hardness of heart.
