My study bible interprets it as saying that the people in Isaiah's time were influenced by the ways of the world, up to the point of saturation! And I'm wondering, are we also saturated and influenced by the ways of this world? If so, how could we change our ways so that we aren't without completely withdrawing from the world?

"You, Lord , have abandoned your people, the descendants of Jacob. They are full of superstitions from the East; they practice divination like the Philistines and embrace pagan customs. Their land is full of silver and gold; there is no end to their treasures. Their land is full of horses; there is no end to their chariots. Their land is full of idols; they bow down to the work of their hands, to what their fingers have made.So people will be brought low and everyone humbled— do not forgive them."

I'd love to hear more thoughts on these verses!
