Some of them came and complained to Moses, saying, “Give us water to drink!” “Why are you complaining to me?” Moses asked. “Why are you trying to challenge the Lord?”
It wasn't long before the people started to complain about how much they were suffering. When the Lord heard what they were saying, he became angry. Fire from the Lord burned them, destroying some on the edge of the camp.
They joined together in opposition to Moses and Aaron, telling them, “You've taken too much power for yourselves! Every one of the Israelites is holy, and the Lord is among them. So why do you set yourselves above the Lord's assembly?”
While you had the land, didn't it belong to you? And after you sold it, didn't you still have control over what you did with the money? Why did you decide to do this? You haven't lied to human beings, but to God!”
Such people are grumblers, always complaining. They follow their own evil desires, speaking boastfully about themselves, and flattering others to get what they want.
