What does Ezra 10:13 mean?

But they added, 'There's a lot of us, and it's the rainy season—we can't all stand out here. Plus, this isn't something we can fix in a day or two, because so many people are involved.' Ezra 10:13 - Modern Text Bible

(They point out the practical challenges: the weather is bad, and the problem is widespread, so it'll take time to sort out.)
