What function did the gatekeepers serve?

Ezra 2:42 (ESV)

42 The sons of the gatekeepers: the sons of Shallum, the sons of Ater, the sons of Talmon, the sons of Akkub, the sons of Hatita, and the sons of Shobai, in all 139.

Gatekeepers guarded the entrance to the temple to prevent it from being desecrated. There would be a lot of silver and golden vessels stored in the temple after it was rebuilt. These people were also Levites (Ezekiel 44:14).
