Pinnacle

a little wing, (Matt. 4:5; Luke 4:9). On the southern side of
the temple court was a range of porches or cloisters forming
three arcades. At the south-eastern corner the roof of this
cloister was some 300 feet above the Kidron valley. The
pinnacle, some parapet or wing-like projection, was above this
roof, and hence at a great height, probably 350 feet or more
above the valley.
