Isaiah 57:7-8

7Upon a lofty and high mountain hast thou set thy bed: even there thou wentest up to offer sacrifice. 8Behind the doors also and the door posts hast thou set up thy remembrance: for thou hast uncovered thyself to another than me, and hast gone up; thou hast enlarged thy bed, and made thee a covenant with them; thou didst love their bed where thou sawest it .12
