The Definition of the word Pinnacle

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.
