'All night' in the Bible

I regret that I have set up Saul to be king, for he has turned back from following me, and has not performed my commandments. And Samuel was angry, and he cried out to LORD all night.

all the valiant men arose, and went all night, and took the body of Saul and the bodies of his sons from the wall of Beth-shan, and they came to Jabesh, and burnt them there.
