All thy strong holds shall be like fig trees with the firstripe figs: if they be shaken, they shall even fall into the mouth of the eater.
All thy strong holds - on the borders of Assyria, protecting the approaches to Nineveh: "the gates of thy land" (Nahum 3:13).
Shall be like fig trees with the first-ripe figs - expressing the rapidity and ease of the capture of Nineveh (cf. Isaiah 28:4, "The glorious beauty which is on the head of the fat valley (of Samaria, or Ephraim) shall be ... as the hasty (early ripe) fruit before the summer; which when he that looketh upon it seeth, while it is yet in his hand, he eateth it up;" Revelation 6:13).
