Darby
9 In that day shall his strong cities be as the forsaken tract in the woodland, and the mountain-top which they forsook before the children of Israel; and there shall be desolation.
KJV
9 In that day shall his strong cities be as a forsaken bough, and an uppermost branch, which they left because of the children of Israel: and there shall be desolation.
