Charles Ellicott Commentary Isaiah 27:11

"When the boughs thereof are withered, they shall be broken off; the women shall come, and set them on fire; for it is a people of no understanding: therefore he that made them will not have compassion upon them, and he that formed them will show them no favor." — Isaiah 27:11 (ASV)

When the boughs thereof are withered ... —The picture of the wasted city receives another touch. Shrubs cover its open spaces (perhaps the prophet thinks of the gardens and parks within the walls of a city like Babylon), and women come, without fear of trespassing, to gather them for firewood.

For it is a people of no understanding. —The words are generic enough, and may be applied, like similar words in Isaiah 1:3; Jeremiah 8:7; Deuteronomy 32:28, to Israel as apostate, or to the world-power, which was the enemy of Israel. In this case, as we have seen, the context turns the scale in favour of the latter reference. So taken, the words are suggestive, as witnessing to the prophet’s belief that the God of Israel was also the Maker and the Former of the nations of the heathen world.
