'Murmurings' in the Bible

How long'shall I bear with this evil congregation, that murmur against me? I have heard the murmurings of the children of Israel, which they murmur against me.

And it shall come to pass, that the rod of the man whom I shall choose shall bud: and I will make to cease from me the murmurings of the children of Israel, which they murmur against you.

And Jehovah said unto Moses, Put back the rod of Aaron before the testimony, to be kept for a token against the children of rebellion; that thou mayest make an end of their murmurings against me, that they die not.
