'Fenced' in the Bible

So the king of the north shall come, and cast up a mount, and take the most fenced cities: and the arms of the south shall not withstand, neither his chosen people, neither shall there be any strength to withstand.

Peaceably even into the fertile places of the province He cometh, and he hath done that which his fathers did not, nor his fathers' fathers; prey, and spoil, and substance, to them he scattereth, and against fenced places he deviseth his devices, even for a time.
