'Hedges' in the Bible

Why hast Thou broken down its hedges, And all passing by the way have plucked it?

Thou hast broken down all his hedges, Thou hast made his fenced places a ruin.

Howl, Heshbon, for spoiled is Ai, Cry, daughters of Rabbah, gird on sackcloth, Lament, and go to and fro by the hedges, For Malcam into captivity doth go, His priests and his princes together.

Thy crowned ones are as a locust, And thy princes as great grasshoppers, That encamp in hedges in a day of cold, The sun hath risen, and it doth flee away, And not known is its place where they are.
