'Watching' in the Bible

One day--it was a Sabbath--He was taking a meal at the house of one of the Rulers of the Pharisee party, while they were closely watching Him.

So, after impatiently watching their opportunity, they sent spies who were to act the part of good and honest men, that they might fasten on some expression of His, so as to hand Him over to the ruling power and the Governor's authority.
