heres a scholar from the same article saying what I was about the amount of people
One scholar who has doubted the authenticity of this temple incident is Paula Fredriksen, who writes in
From Jesus to Christ that she learnt quite a bit about the temple from Sanders' book
Judaism: Practice and Belief (1992), including the temple's measurements, which she describes as follows: "The total circumference of the outermost wall ran to almost 9/10ths of a mile; twelve soccer fields, including stands, could be fit in; when necessary (as during the pilgrimage festivals, especially Passover) it could accommodate as many as 400,000 worshipers."
[73]
When Fredriksen visited the Temple Mount, she was aghast at how huge it was, and its size "shrank" Jesus' alleged action, prompting her to ask herself:
If Jesus
had made such a gesture, how many would have seen it? Those in his retinue and those standing immediately around him. But how many, in the congestion and confusion of that holiday crowd, could have seen what was happening even, say, twenty feet away? Fifty feet? The effect of Jesus' gesture at eye-level would have been muffled, swallowed up by the sheer press of pilgrims. How worried, then, need the priests have been?
[74]
Needless to say, her confidence in the historicity of the temple scene diminished as she contemplated these questions, and she states as much in the referenced article.
Had Jesus' action been as disruptive as portrayed in the Gospels, the Roman soldiers would have arrested Jesus or forcefully restored order because, as Josephus intimates in
Antiquities of the Jews 20.5.3 and
Wars Of The Jews 2.12.1, the Romans always had soldiers on stand-by during Passover because riots were particularly likely then. The Roman administration also needed the taxes that the moneychangers and other traders paid, and they would not watch idly as the temple activities were disrupted by a lone man.
