▼ The figure is aposiopesis, or sudden silence. The main verb is deleted from the line, “how long…this evil community.” The intensity of the emotion is the reason for the ellipsis.

▼ It is worth mentioning in passing that this is one of the Rabbinic proof texts for having at least ten men to form a congregation and have prayer. If God called ten men (the bad spies) a “congregation,” then a congregation must have ten men. But here the word “community/congregation” refers in this context to the people of Israel as a whole, not just to the ten spies.
