Lift up thine eyes unto the high places, and see where thou hast not been lien with. In the ways hast thou sat for them, as the Arabian in the wilderness; and thou hast polluted the land with thy whoredoms and with thy wickedness.
High places - the scene of idolatries, which were spiritual adulteries.
In the ways hast thou sat for them - watching for lovers like a prostitute (as Tamar did, Genesis 38:14; Genesis 38:21; Proverbs 7:12; Proverbs 23:28; Ezekiel 16:24-25), and like an Arab who lies in wait for travelers. The Arabs of the desert, east and south of Palestine, are still notorious as robbers.
