Then the devil taketh him up--rather, "conducteth Him." into the holy city--so called (as in Isa 48:2; Neh 11:1) from its being "the city of the Great King," the seat of the temple, the metropolis of all Jewish worship. and setteth him on a pinnacle of the temple--rather, "the pinnacle"--a certain well-known projection. Whether this refers to the highest summit of the temple, which bristled with golden spikes [JOSEPHUS, Antiquities, 5.5,6]; or whether it refers to another peak, on Herod's royal portico, overhanging the ravine of Kedron, at the valley of Hinnom--an immense tower built on the very edge of this precipice, from the top of which dizzy height JOSEPHUS says one could not look to the bottom [Antiquities, 15.11,5]--is not certain; but the latter is probably meant.
