'Murmur' in the Bible

and in the morning, then you shall see the glory of Yahweh; because he hears your murmurings against Yahweh. Who are we, that you murmur against us?"

Moses said, "Now Yahweh shall give you meat to eat in the evening, and in the morning bread to satisfy you; because Yahweh hears your murmurings which you murmur against him. And who are we? Your murmurings are not against us, but against Yahweh."
