'Discontented' in the Bible

You murmured and were ill-tempered (discontented) in your tents, and said, ‘Because the Lord hates us He has brought us from the land of Egypt to hand us over to the Amorites to destroy us.

Everyone who was suffering hardship, and everyone who was in debt, and everyone who was discontented gathered to him; and he became captain over them. There were about four hundred men with him.
