Woe unto them... — The words sound like an echo of Isaiah 5:8; Isaiah 5:11; Isaiah 5:18, and show that Isaiah had not lost the power of adding to that catalogue of woes. The sins of which he speaks here may have been either the dark sensualities which lay beneath the surface of religion, or, more probably, their clandestine intrigues with this or that foreign power — Egypt, Ethiopia, Babylon — against the Assyrian invader, instead of trusting in the Lord of hosts.
