'Quickly' in the Bible

Now therefore send quickly, and tell David, saying, Lodge not this night in the plains of the wilderness, but speedily pass over; lest the king be swallowed up, and all the people that are with him.

Nevertheless a lad saw them, and told Absalom: but they went both of them away quickly, and came to a man's house in Bahurim, which had a well in his court; whither they went down.

And it came to pass, after they were departed, that they came up out of the well, and went and told king David, and said unto David, Arise, and pass quickly over the water: for thus hath Ahithophel counselled against you.
