Mishnayos Shekalim Perek 3 Mishnah 3

In order to indicate the importance that was attached to the ceremony of the collection of the Temple treasury chamber, the mishna relates that the members of the house of Rabban Gamliel desired that their shekels be the ones collected from the chamber and used for the purchase of the communal offerings. Each of them would therefore come to the Temple specifically on the day of the ceremony of the collection of the chamber, enter the chamber with his shekel between his fingers, and toss it in front of the one collecting the money so that he would see it and place it in the basket containing the money to be taken out of the chamber. Understanding what was happening, the one collecting the money from the chamber would purposely push this shekel into the basket, so that it would later be used to buy communal offerings. The one collecting the funds from the chamber may not begin to collect the money until he asks the Temple treasurers three times: Shall I collect the funds, and they say to him: Collect them, collect them, collect them, three times.
