'Doing' in the Bible

So the Pharisees said to him, "Look, why are they doing what is against the law on the Sabbath?"

If anyone says to you, 'Why are you doing this?' say, 'The Lord needs it and will send it back here soon.'"

Some people standing there said to them, "What are you doing, untying that colt?"

and said, "By what authority are you doing these things? Or who gave you this authority to do these things?"

So they answered Jesus, "We don't know." Then Jesus said to them, "Neither will I tell you by what authority I am doing these things."
