ISA 57:8

8 Behind the delet also and the mezuzah [(doorpost)] hast thou set up thy zikron [([pornographic and idolatrous] memorial)]; deserting Me, thou hast uncovered thyself, and art gone up; thou hast enlarged thy mishkav [(bed)] and cut for thee with them [a Brit]; thou lovedst their mishkav [(bed)] where thou hast looked on their yad.
