Nehemiah 4:3

If a fox go up He mentions foxes because they were very numerous in those parts, and because in the late desolation of Jerusalem, the foxes did frequent the mount and city of Zion, (Lamentations 5:18,) wherewith he seems to upbraid them. He shall even break down their stone wall It is so low that a fox can easily ascend to the top of it, and so weak, and built so hastily and carelessly, that the least weight or thrust will tumble it down.
