This verse describes what God will do to the land of Israel.

And I will make the land a desolation and a waste: See 6.14. Contemporary English Version says “I will make the whole country an empty wasteland.”

And her proud might shall come to an end: Compare 30.18. God will end the power that gave the Israelites pride. Israel will no longer be a strong and significant country. Her proud might refers to Israel’s arrogant confidence in her strength and military power (see the comments on 30.6). For this whole clause Good News Translation says “and the power they were so proud of will come to an end,” and New Living Translation has “Her arrogant power will come to an end.” Another possible model is “I will put an end to the power they were so proud of.”

And the mountains of Israel shall be so desolate that none will pass through: The mountains of Israel was the area where the Israelites originally settled and which remained the core of the country (see the comments on 6.2). The Hebrew verb rendered desolate comes from the same root as the noun translated desolation. It may be rendered “bare” (Contemporary English Version), “empty” (New Century Version), or “deserted” (New International Reader’s Version, Jerusalem Bible/New Jerusalem Bible, Christian Community Bible, Moffatt). The mountains will be so barren that none will pass through, that is, no one will live there and no one will travel through the area (compare 29.11).
