Isaiah 57:8

The posts — Behind the posts of the doors of thine house: where the Heathens placed their tutelar gods to whose protection they committed their houses, that so they might have their eyes and minds upon them, whensoever they went out or came in. Set up — Those monuments which thou didst set up there as remembrances of those idol — gods whom they represented. Discovered — Thou hast uncovered thy nakedness; to others beside me thine husband. Gone up — Into the adulterous bed. Enlarged — That it might receive many adulterers together. Thou hast multiplied thine idols and altars. A covenant — Thou hast covenanted to serve them.
