'All night' in the Bible

"It grieves me that I have made Saul king; for he has turned back from following me, and has not carried out my commandments." And Samuel was angry; and he cried to the 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.
