NET

15 Then the king of the north will advance and will build siege mounds and capture a well-fortified city. The forces of the south will not prevail, not even his finest contingents. They will have no strength to prevail.

Darby

15 And the king of the north shall come, and cast up a mound, and take the well-fenced city; and the arms of the south shall not withstand, neither his chosen people, for there shall be no strength to withstand.

KJV

15 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.
