and they rose up, and cast him forth out of the city, and led him unto the brow of the hill whereon their city was built, that they might throw him down headlong. (ASV)

Go ye forth unto the land of Google.com, in the country of Earth therein, that be at: http://earth.google.com, and download unto the the tablet of code that be called “Google Earth.” Installeth thee that tablet of code into thine computer which hath the Windows of the Firmament of Redmond, then causeth thou it to run. Thou shalt check the “Terrain” checkbox, that the hills might be plainly visible. Setteth thee the Options that the Terrain Exaggeration be set unto one, not unto three nor two nor any other number, that thou mayest see the hills as they do actually be.
Firstly searcheth thou for “San Francisco, CA”, and tilteth thou the angle of the camera, and rotate it round about, that thou might plainly see that the Tablet of the Earth of Google canst indeed show unto thee such hills as do truly exist.
Now pointeth thou the tablet of code towards “Nazareth, Israel”, and likewise tilteth thou the angle of the camera, and rotate it round about, that thou shalt see all the hills that be within and nearby Nazareth. Rememberest thou that Luke sayest of the hill that it hath a brow tall and steep enough that they that liveth there didst honestly believe that any man hurled therefrom wouldst surely die. Rememberest also that Luke sayest that, while they didst take Him outside the city, of the hill he didst say, “upon which their city was built.” This meaneth that at least part of the hill must needs lie within the ancient city limits of Nazareth.
And yet, seest thou any such hill, even within the much larger modern city limits which completely containeth the ancient? Nay, no such hill canst be found, neither in the Earth of Google, nor in any topographic maps available from any source, nor even in the aereal photographs of Nazareth that canst be found in the flyers and brochures made by the merchants of Bible tours sold to they who follow Christ, that they mayest Walk Where Jesus Walked (for a price of many shekels)! Surely, they that selleth such tours wouldst have reason to show such a hill, if indeed such a hill existed. And yet, none such hill hath ever been found, even though hundreds of learned and wise men hath searched for many centuries.
From Robertson's Word Pictures of the New Testament located here 
Unto the brow of the hill (hov opruov tou orouv). Eyebrow (opruv), in Homer, then any jutting prominence. Only here in the N.T. Hippocrates speaks of the eyebrow hanging over.
That they might throw him down headlong (wste katakrhmnisai auton). Neat Greek idiom with wste for intended result, "so as to cast him down the precipice." The infinitive alone can convey the same meaning (Matthew 2:2; 20:28; Luke 2:23). Krhmnov is an overhanging bank or precipice from kremannumi, to hang. Kata is down. The verb occurs in Xenophon, Demosthenes, LXX, Josephus. Here only in the N.T. At the southwest corner of the town of Nazareth such a cliff today exists overhanging the Maronite convent. Murder was in the hearts of the people. By pushing him over they hoped to escape technical guilt.
From A Critical and Exegetical Commentary on the Gospel According to St. Luke by Alfred Plummer located here 
29. Tradition makes the scene of this attempt to be a precipice, varying from 80 to 300 feet in height, which exists some distance off to the S.E. of the town ; and we read that " they cast Him out of the town and led Him as far as the brow," etc. But modern writers think that a much smaller precipice close at hand is the spot. Van der Velde conjectures that it has crumbled away ; Conder, that it is hidden under some of the houses. Stanley says that Nazareth " is built ' upon,1 that is, on the side of, 'a mountain' ; but the 'brow' is not beneath, but over the town, and such a cliff as is here implied is to be found, as all modern travellers describe, in the abrupt face of the limestone rock, about 30 or 40 feet high, overhanging the Maronite Convent at the S.W. comer of the town"...Both AV. and RV. have "the brow of the hill whereon," which might easily be misunderstood. The town is on the hill, but not on the brow of it: the brow above the modern village.
Edit this section to note miscellaneous facts.
Even though I really like the Style here the related question is:
Where was the Nazareth that "Luke" referred to?
The answer to this question will determine if there is error and Who's error it is.
In the meantime, I sense a disturbance in The Force:
"The Verse" is strong in this One. Rather than answer the question this article shows the diffiCulty in answering the question. But, as Chief Inspector Clouseau says, "Now we are getting somewhere!" (Just not to Nazareth).
