On a high and lofty mountain you have set your bed. You also went up there to offer sacrifice. You have set up your memorial behind the doors and the posts, for you have exposed yourself to someone besides me, and have gone up. You have enlarged your bed and made a covenant for yourself with them. You loved what you saw on their bed. You went to the king with oil, increased your perfumes, sent your ambassadors far off, and degraded yourself even to Sheol. You were wearied with the length of your ways; yet you didn’t say, ‘It is in vain.’ You found a reviving of your strength; therefore you weren’t faint.
