'All night' in the Bible

"It grieves me that I have set up Saul to be king; for he is turned back from following me, and has not performed my commandments." Samuel was angry; and he cried to Yahweh 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.
