“And they became a sign”
Numbers 26.10
Here in the Book of Numbers the Lord is reminding the children of Israel about some men who stood up against God. They had decided that God got it wrong when He chose Moses and Aaron to be the leaders of Israel. The whole verse says, “And the earth opened her mouth, and swallowed them up together with Korah, when that company died, what time the fire devoured two hundred and fifty men: and they became a sign.”
