'Suddenly' in the Bible

Samson went down to Timnah with his father and mother and came to the vineyards of Timnah. Suddenly a young lion came roaring at him,

They were having a good time, when suddenly some men of the city, some good-for-nothings, surrounded the house and kept beating on the door. They said to the old man who owned the house, "Send out the man who came to visit you so we can have sex with him."
