Isaiah 57:8

Behind the doors also and the posts, within the house devoted to idolatry, hast thou set up thy remembrance, the memorial tablet reminding the apostates of their idols; for thou hast discovered (uncovered) thyself to another than Me and art gone up, namely, to the couch of sin; thou hast enlarged thy bed and made thee a covenant with them, agreeing upon a price of shame; thou lovedst their bed where thou sawest it, delighting in the filthiness of the spiritual adultery thus openly practiced, the shamelessness thus brazenly paraded.
