'Watching' in the Bible

So the scribes and the Pharisees were watching closely [to see] if he would heal on the Sabbath, in order that they could find [a reason] to accuse him.

And it happened that when he came to the house of a certain one of the leaders of the Pharisees on a Sabbath to eat {a meal}, they were watching him closely.

And the people stood there watching, but the rulers also ridiculed [him], saying, "He saved others; let him save himself, if this [man] is the Christ of God, the Chosen One!"
