1 Corinthians 10:10, Neither murmur Ye
The Israelites in the wilderness were constantly murmuring, dissatisfied with their present state, grumbling and complaining. Their murmurings were against God. For He brought them out of Egypt by reason of their bondage and showed them the way to the Promised Land, a land flowing with milk and honey. The murmuring of Korah, Dathan, and Abiram against Moses and Aaron is highlighted here – Numbers 16:1-3 Now Korah, the son of Izhar, the son of Kohath, the son of Levi, and Dathan and Abiram, the sons of Eliab, and On, the son of Peleth, sons of Reuben, took men: And they rose up before Moses, with certain of the children of Israel, two hundred and fifty princes of the assembly, famous in the congregation, men of renown: And they gathered themselves together against Moses and against Aaron, and said unto them, Ye take too much upon you, seeing all the congregation are holy, every one of them, and the LORD is among them: wherefore then lift ye up yourselves above the congregation of the LORD?
