Translation of the verse 62 from Surah Ta-Ha : Number of verses 135 - - page 315 - Part 16.
Then they debated with one another what they must do, and they kept their talk secret.
So they disputed over their affair among themselves and concealed their private conversation.
(20:62) Hearing this, a difference of opinion arose among them concerning the issue, and they began to hold secret consultations. *35
*35) This shows that those people felt in their hearts that their position was weak and knew that the miracle shown by Prophet Moses was not a piece of magic. Therefore, they had come for the encounter with hesitation and fear. But when the timely, sudden warning of Prophet Moses shook them to the core, they began to debate the wisdom of holding the encounter on the Feast Day in an open place in the broad day light. For they thought that if they were defeated in the presence of the common people, all would come to know of the difference between magic and a miracle and they would lose the battle once for all.
